Fourier equation and getting out of memory error tia sal22

Fourier equation and out of memory error tia sal22 Sorry is this got posted twice my posts seem not to be showing up in some groups...usenet gremlins again Greetings All I can get this matalb script to work and plot when I set x=linspace(0,1,100); But when I set x=linspace(0,1,44100); I get a mtimes out of memory which I narrowed down to the large array size in the C and S variables Can someone recommend a way for this code to work without running into memory errors? I tried going the fft route but the signal would never match up. The plot looks great I just would like to:

Problem compiling mex function

Hello, I am trying to compile a .mex file that grabs data from a National Instruments high-speed digitizer card. I have the code working on an older machine (32bit windows XP with Matlab 7.0.1), but am running into linker errors on a new machine (64bit windows 7 with 64bit Matlab 7.10.0). When I try to mex the .cpp file I get the following linker errors: mex('-v', ... '-LC:\Program Files (x86)\IVI Foundation\IVI\Lib\msc\', ... '-lniScope', '-livi','-liviscope', ...

3d plot with multiple 2d plot contours

I need to draw a 3d plot as follows: There are three planes that are parallel. on each plane I wish to draw a 2d plots like contours or multiple circles. I also want to draw the planes and draw arrows that connect the some points inside the planes.

Structure Assignment

Given vectors x and y each with N elements, I want to create an N element structure s with fields s.x and s.y. I can do this by for ii=1:N, s(ii).x=x(ii); s(ii).y=y(ii); end I there a neater way?

Polynomial Model Template

Dear all, I want to use polynomial model template of order -'n' (should be input by user) of m factors (the symbols should be input by user) in MATLAB. Using Model-Based Calibration toolbox [my matlab version: MATLABR2009a] it can be done in GUI. But I want to do this in .m file invoking some inbuilt function of MATLAB (or more specifically MBC toolbox). I am not able to figure out which function I should invoke to do this. Please help me in this regard. BR Samiran.

p-value

Hi Everyone, Suppose I have a vector containing standard errors for an OLS regression model. Now I wish to obtain a corresponding vector that contains the p-values for these standard errors. Given that I do not have the MatLab statistics toolbox, how do I go about obtaining this result? Regards, Ulrik

Find nonzero rows in matrx

Is there a simple method (or a function) that you can use to find nonzero rows in a matrix. So, suppose I have a matrix A: A = [ 1 0 0 2 3 5 0 4 3 1 0 5] Row 2 has only nonzero elements, while rows 1, 3 and 4 have some zero elements. I would nou like to get the index of the "nonzero row", which in this case is 2 of course. Can anyone help? Tanks!

voronoin

Hello, I need to create the Voronoi Diagram of a group of kidney cells. I have centroid coordinates (3D) of every cells. I open the file (called 'Glomerulo') with the coordinates and then: x=Glomerulo(:,1); y=Glomerulo(:,2); z=Glomerulo(:,3); B=[x y z]; #creation of the centroids matrix [v, C]=voronoin(B) #3D voronoi diagram of B NOW: HOW CAN I PLOT MY DIAGRAM? Thanks

Function References

Hi! I would like to know if there is way to generate a report listing all the classes that are a using a particular function on a particular class. For example, I have the MyFunction1 function on the MyFile1.m, and I would like to know all the m files and other files using the MyFile1.MyFunction1. Thanks!

create .avi files from different video and audio streams

I am doing a project where I separate video and audio data from an .avi file, then I proccess them somehow(doesn't matter) and I want to create an output .avi file combining the new audio and video data. Firstly, I found it hard to get the audio from an .avi file but finally I used the -mmread- function from Micah Richert and manage to read both audio and video data. Now can't find a way to get the new data together to a new .avi file.Of course there is -mmwrite-, but because I change the format of the video and audio structs that -mmread- returns is difficult to use. One way is to try

Inverse Bump Mapping

Hi Folks, Does anyone know of a tool or a way to approach converting a bump mapped 2D image into a 3D relief map. e.g. Using an image like this http://www.blacksmith-studios.dk/images/projects/bumpmapping_tut/rockBump.JPG extract an estimate for the surface profile or a cross-section if the illumination angle is known. cheers in advance for any poke in the right direction!

Flattening 3d surfaces

Dear community, is there any tool to unwind (simply) warped (triangulated) 3d surfaces, e.g. the surface shell of a cylinder (height h, radius r), which should then result in a rectangle of height h and width 2*pi*r. I know that the resulting surface will be nonoverlapping only in some cases, especially not in the case of bidirectional warped surfaces. My ideas towards such an algorithm are the following: 1. Start from some triangle of the triangulated surface. 2. go through all edges and "flatten" the adjacent triangles by rotating the non-common cornerpoint around the sharted ed

problem: creating a decimal to binary function for an array input

Hi People, I'm trying to create a decimal to binary function for an array input but it seems that my output is always wrong, I believe it has something to do with the loop. This is my code clear; clc; %%input x=1; dec_nr = [1 2; 255 245; 1 255]; %% accessing row for row = 1:3 %% accessing column for column = 1:2 i=1; q(row,column) = floor(dec_nr(row,column)/2); r(row,column) = rem(dec_nr(row,column), 2); bin(x,:) = zeros(1,8); bin(x,i) = r(row,column); while 2 <= q(row,column); dec_nr(row,column) = q(row,column); i = i + 1; q(row,column) = floo

texture removal

Hello I want to read some alphanumeric data printed on a textured background, a sample image of which I have uploaded here. http://drop.io/texture11 I would like to erase the background texture, so that only the alphanumeric character stand out. Later I need to do OCR, which I think I can be able to do, but segmentation right now is possing a problem. using ; background = imopen(I,strel('disk' ,10)); does not help Thanks Vihang

function for number of elements less than something?

Is there a way to simply return the number of elements in an array that is less than a given number. I'm currently doing it the way I would in C but I know matlab probably has a better way! for k=1:length(x_coords) if x_coords(k) < thresh points_before_start = points_before_start + 1; end end Thanks

reading parameter from s-function block

Hi everyone, I'm working on a CAN driver and we are adding a functionality named: Gateway. this block needs the following parameters: CanSrcBus, CanDesBus, CanIdMask, CanGwBidirectional. the CanIdMask is a parameter that can contain more then one variable and is used for comparison with CANId's. In the S-function C, i use the following lines for getting the parameters: uint8_T CanSrcBus = (uint_T)(mxGetPr(ssGetSFcnParam(S, S_CANSRCBUS_ARG))); uint8_T CanDesBus = (uint_T)(mxGetPr(ssGetSFcnParam(S, S_CANDESBUS_ARG))); int32_T CanIdMask = (uint_T)(mxGetPr(ssGetSFcnParam(S, S_CANI

pcode and MEX is not useful when MCR is "version dependent"

matlab can generate p-code and executable file by mcc command but how it can be useful when they are depend on MCR VERSION? it is depend on MCR and i have no problem with it but the version must be the same in the end-user pc. i mean when i write a code on matlab 7.5 and Runtime7.7 and for any reason dont want to show source to any other, i have no way. i can use p-code but the end user can not run my code when he have a different matlab version (and MCR) installed. this version related MCR is a big problem. or is there any other way to run a matlab program on end user computer that i do

system command string error

Hi everyone, I am trying to use the system command to open a new instance of matlab and pass a function into it, the call is something like this: system('C:\MATLAB\R2009b\bin\matlab -nosplash -minimize -r myFun(''read:=test.txt'')') When this runs it gives me the following message: ??? Error: A MATLAB string constant is not terminated properly. I have to use myFun with this specific type of input and I am 100% positive the error has to do with those double quotes around the input argument but I can't for the life of me figure out how to get this to work. Note: those double

Concatenation in Simulink

Hi, Two constant arrays 2x2 were defined using Source Blocks in Simulink. They were concatenated (e.g. horizontally). Result was assigned to the variable zz using 'To Workspace' block. If the 'To Workspace' block parameter 'Limit data points to last' is equal to 1 than zz is 2x4 matrix. If 'Limit data points to last' is the default inf or 2 than zz is 2x4x2 matrix, two identical 2x4 matrices in two planes. Why is 2x4x2 matrix in the latter case? Regards, Pavel
