matlab help in fsolve

this is my matlab main file:

a=[];

    display(i);
c0 = [i; 0; 0; 0; 0];           % Make a starting guess at the solution

options=optimset('Display','iter');   % Option to display output

[c] = fsolve(@myfunction,c0,options);  % Call optimizer

a=[a c(5)];
display(a);
end
i=0:100:600
display(a);
%plot(i,a)
plot(i,c(5,:))

It's no error message - MATLAB tells you that FSOLVE successfully
determined a solution within the given tolerance.

These "exit messages" can be confusing, you are certainly not the only 
person who got tripped up on them. Optimization Toolbox has new exit 
messages that are supposed to be clearer and friendlier. The fsolve exit 
messages were improved in R2009b, fmincon in R2009a.

Help with Parallel Matlab
Long story short, here is the criteria I need. 1) I need two modules running in parallel. One function must activate these two They don't need to START at the same time but both neither return info nor end. They run pretty much infinitely 1.1) I would prefer if the One function also ran separate from the above two in it's own loop but i can deal with a 3'rd function also not ending. 2) I need a shared variable between two of the modules. 1 Module will place information there while the other just reads it, but as they are running parallel. That's it. I can do this in pretty much any other language but matlab I've been having issues with. Problem is I absolutely need to use matlab for one module. If this is impossible to accomplish all in matlab then can i instead run this in C and call one matlab module with separate thread? Sample code below. function mainParallelTest() persistent counter; counter = 0; parfor i=0:2 if (i == 0) ImageProccessorParallelTest(); elseif(i == 1) EventProcessorParallelTest(); elseif(i == 2) prevCounter = 0; tempCounter = 1; while(true) tempCounter = counter; if (tempCounter == prevCounter) %disp('hi') end prevCounter = tempCounter; end end end "Alex Cruikshank" <cruiksam@gmail.com> writes: > Long story short, here is the criteria I need. >...

Help with Matlab Problem
Any one know how to work this problem? In this exercise you are to compute a power of the diagonalizable matrix A. Let A = pascal(5).

AToNinth = (A+0)^9; The exercise just said you couldn't apply ^ to A; it said nothing about the expression A+0.

Need Help With Matlab
Hi I am trying to simulate the low pass filtered output of a square wav (pulse train) using Matlab. The pulse varies between 0 and 1. So th filtered output looks somewhat like a sinewave. The filter is a low pas filter (FIR/raised cosine filter). Essentially what I need is to be abl to generate a look up table that will store the output waveform rise fall transition (from 0-1 and 1-0). So what i want essentially is to b able to generate a look up table of different lengths (like 100,50 etc) t store these transitions. I tried using Simulink for this, but havent bee successful so far. So my table will look something like 1 0.995 0.923 0.91 0.85 ..... to 0 Any help is highly appreciated. Thanks.

Best copy I have, evidently I deleted the working copy and for the life of me, I can't fix it. Any good people out there that can help edit this crazy thing back to health? See code below, relatively straightforward, but its not compiling...I dunno.

hello. i am having some problem on demodulating my signal maybe some one can help me below is my code %% create DATA fc=13.56E6; % carrier frequency fm=fc/32; % modulation frequency fs=fc*4; %sampling frequency tb=512/fc; %time length of 1 bit To=8*tb; %length of 8 bit hex_string='AF'; % string in hexadecimal format dec_string= hex2dec(hex_string); % convert hexadecimal string to decimal input=dec2bin(double(dec_string),8); % convert decimal string to binary dataCh=0; for j=1:length (dec_string) dataCh=[dataCh input(j,1:8)]; end; dataCh=dataCh(2:length(dataCh)); input=double(dataCh)-48; Ns=tb*fs; %The required number of sample to 1 bit %% MANCHESTER CODING i=1; while i<=length(input) switch input(i) case 0 for j=1:2:15 output((i-1)*Ns+1+(j-1)*Ns/32:(i-1)*Ns+j*Ns/32)=4; end for j=2:2:16 output((i-1)*Ns+1+(j-1)*Ns/32:(i-1)*Ns+j*Ns/32)=0; end for j=16:32 output((i-1)*Ns+1+(j-1)*Ns/32:(i-1)*Ns+j*Ns/32)=0; end case 1 for j=1:16 output((i-1)*Ns+1+(j-1)*Ns/32:(i-1)*Ns+j*Ns/32)=0; end for j=17:2:31 output((i-1)*Ns+1+(j-1)*Ns/32:(i-1)*Ns+j*Ns/32)=4; end for j=18:2:32 output((i-1)*Ns+1+(j-1)*Ns/32:(...

Matlab builder JA: parse java string to matlab cell
Hi all, I'm building a java swing based GUI for my Matlab application. As such, user input is available as text strings, for example "{[0; 0], [3.5 0; 0 2]}" (mean vector and covariance matrix of a 2D Gaussian). The user input will be passed to the compiled matlab method as a MWCellArray. Problem is how do a convert (parse) the above string into a MWCellArray? From its javadoc http://www.mathworks.com/access/helpdesk/help/toolbox/javabuilder/MWArrayAPI/index.html the following method is available: java.lang.String toString() Returns a string representation of this array, but the reverse method is not. Evidently, parsing a string like the one above is a non trivial task and I'm loath to attempt writing one by myself. I would be very thankful if someone can point me to the required parser implementation. Matlab itself is carrying out this task all the time, perhaps it is possible to access Matlab's own parser. Help much appreciated, Ritesh ...

Help add functionality to MATLAB
Dear MATLAB community, Please help add custom Distribution Fitting Functions & Negative Log-Likelihood Functions to the statistics toolbox that matlab provides. I am looking at the documentation, as seen here, http://www.mathworks.com/help/toolbox/stats/bqt29ct.html, and here, http://www.mathworks.com/help/toolbox/stats/f4218.html#bqt4w61 You will notice that MATLAB does not provide Distribution Fitting Functions & Negative Log-Likelihood Functions for the "continuous distributions (statistics)" set of distributions, as they do for the "continuous distributions (data)" set of distributions. This is functionality that could be used if a data set had a non-central chi squared distribution, for example. This can and does happen in the world of data. The non-central chi squared distribution is NOT only a distribution used for statistical analysis. I would try to do this myself, but I do not want to screw it up, and it is slightly above my head to create this properly. I implored the Mathworks to consider adding this functionality over 2 years ago and it has not been looked at. Please help improve MATLAB. I just noticed that the first link is not working properly because of the comma at the end of the link. So, just use this link: http://www.mathworks.com/help/toolbox/stats/bqt29ct.html The Mathworks may or may not see this. Your best bet is to send an email request to support@mathworks.com or call them on the phone. On Feb ...

Matlab student license for MDSD (e.g. Matlab Coder)
Hello, I'm evaluating products for writing my final university thesis. I want to perform image processing algorithms (C-Code compiled for a DSP). I have the feeling that manual programming of this algorithms is no longer state of the art. Instead MDSD (model driven software development) - that means Code Generation - seems to be smarter to me. Unfortunately Mathworks offers no licenses of Matlab Coder (or Simulink Coder etc.) to individual students. And I cannot afford to buy a commercial license (which probably would cost me more than 5.000 EUR/$ / my absolute limit is 1.000 EUR/$). Is there any possibility for me to use MDSD (code generation) for image processing for my university thesis ? Maybe by using cheaper alternatives ? Or by using 3d party software (like target link) ? Or export/import to another product ? Any idea ? (I want to avoid manual coding - like using OpenCV) By the way, does anyone know, why Mathworks hides the MDSD features from students ? It doesn't make sense to me that Mathworks reduces the amount of engineers available on the job market that are capable of handling (serious) Matlab projects. (Microsoft offers the "Visual Studio Express Edition" for free for education and the amount of people on the job market that are experienced in Visual Studio is tremendous.). Thank you, Roelof ...

You should instead get the result of trapz as follows: function I = quiz() ..... ..... I = trapz(a,X); ...
