There's no picture. when I enter the data and say I want a BodePlot, when I click Draw, the grid appears but there's no function drawn, just the crosshair. help!

I've solved the following equation for y[t]. eqn = y'[t] == a (y[t]/((y[t])^2 + b )) - c y[t] + d keqn = eqn /. {a -> 10 , d -> 0.1 , c -> 1 , b -> 10 } ksol = NDSolve[{keqn, y[0] == 0}, y, {t, 0, 200}] Plot[y[t] /. ksol, {t, 0, 200}, PlotRange -> All]; Now I would like to plot the log of y[t] while varying a over a range of values ( 0-40) How will I accomplish this? It seems like I would have to solve the DE while varying a a little at a time then take the log of it? At first I thought the following will do the trick, but it didn't. I was tr...

Hi, I am trying to plot a series of randomly generated line segments. However for some weird reason the following code is not plotting all of them. For example, if I were to set the num variable to 3, it only shows either 1 or 2 lines. If i set it to 6, it only displays 4 lines... I'm lost!! If you need more parts of my code please let me know. Thanks. for i = 1:num if (i == 1) axis([0 film_length 0 film_length]); hold all; end X{i} = originX(i,1):0.1:endX(i,1); Y{i} = slope(i,1) * X{i} + intercept(i,1); p = plot(X{i},Y{i}); if (type...

Hi, in an existing figure i want to plot. I experiment with subplot, but I cannot give a position for the plot.

Hi, I use plot(x_axis, OriginalData); hold all; for trial=1:1000 f = getData(...); plot(x_acis, f); end The different f-functions are all concentrated around "OriginalData" (more or less randomly with some variance). I want to plot now the "envelope" as well as a "density" plot, i.e. where most of the instances lie. I played around with creating a matrix and manually using a counter but that does not only take hours but it's also unreliable (needs to precicly know the dimensions) and the interpolation between the points is ...

Hi, there, Is it possible to set the y axis of plot figure to probability scale? I need to plot some grain-size data, of which the y axis (accumulated percentage) should be in probability scale and the x axis (size) should be in linear scale. Thanks in advance. I don't understand exactly what you want. The built-in axis scales in MATLAB are linear and log. There's a "normplot" function in the Statistics Toolbox that creates a plot on which the y tick marks have labels between 0 and 1 and are spaced according to the quantiles of a normal distribution. If you just w...

I am trying to write a program in Visual Basic that will create a pdf of all dwg files in a folder. The API call "PlotToFile" works just fine if I create a dwf file, but does not work with pdf. It creates the pdf file, but it will not open in Adobe. I have tried two different shareware pdf writer software packages, cutePDF and deskPDF, and neither one work. Is what I am doing possible or am I doing something wrong. As a side note, I can manually create the pdf files with same pdf plotter I configured with the plotter manager. Any help would be greatly appreciated. Thanks...

I want a fit function to be plotted only in a special range: plot [x=0:400] 'Data.txt' using 1:2, [x=100:400] f(x) however seems not to work. Is this somehow possible ? If not, then this could mean that I would have to use another tool, simply because I can not print a fitfuntion in the whole graph because that would mean that the fit is relevant in the whole plot which is not true.

Hello, I'm using surf() to plot a 20x20 matrix. Surf() correctly shows a 20x20 grid in the resulting plot, but the lower X and Y bounds are 0. Since matlab arrays start with element index number '1' and not '0', the lower row/column are empty in the plot. Also, the last row/column of data is lost, even if I change in axis bounds (from 0:20 to 1:21). I know I can fix this error by padding the matrix with one row and column of zeros, but I assume I'm missing something here that would make it easier. Does anyone know how to address this issue? Am I making a mistak...

I'll pare this down to the statement: "I have tried proc mixed instead but I don't like the output it provides." Because PROC MIXED is ideal for a split plot analysis with covariates (and GLM most definitely is not, unless you make multiple runs), I wonder if maybe we couldn't generate the output you are looking for somehow. Could you say what you don't like? As far as what you have, it appears to be "correct" in the sense that the proper error terms are being used to test effects. I would expect separate p values for your dependent variables, as you have ...

Hi all, its been a while... I am writing some ocean scripts to work out sensitivity of various specifications to design variables. What I would like to do is to process the X values so I can show them in % terms rather than the absolute value set for the design variable being changed. For example, say I am varying a width of a device, and plotting ac- gain. The normal result from the parametric simulation would be a graph of the width on the x axis against the ac-gain on the y axis. However, I want to show the % change from the mean value of the width on the x axis and the % change from the ...

Whenever I plot something using PLOT, the figure is never exactly centered due to the numbers on the left hand side and on the bottom taking up a bit of space and thus displacing the image by that amount. How can I get the image to be EXACTLY centered? I don't need the number info or tick marks or border at all and just want an exactly centered image on the page, but even when I set AXIS to OFF the image is still not centered and acts as if the numbers were still there. ...

Hello, I have a 3d plot, and I'd like to remove (or make transparent) the rear surfaces that bound the plot space (the surfaces corresponding to x=xlim and y=yllim). Essentially, all that should be visible is the z=0 plane, viewed at an angle. I've looked through the documentation and I must've missed how this can be done. Could someone help me with this please? Many thanks, PLH. For now, I've used axis off, although it would be nice to know if it's possible to still retain the x and y axes. "PLH" wrote in message <ih6uss$4up$1@fred.mathworks....

I've done quite a bit of reading over this topic and still can't quite get my code to work. I have three 1 dimensional vectors. The x and y values correspond to cordinates and the z values will be a magnitude reading taken at the x and y cordinates. For example x=[1 4 2 3] y=[5 4 2 6] z=[1.1 1.9 1.6 1.2] I need to make a contour plot of this data. I know I need z to be at least a 2x2 matrix and so the data must be interpolated at the points I don't know. My question is if I know the values below how do I use interp2 to find the '+' values so I can use that re...

Hi, I am having a problem plotting a graph in real time. Here are the details: I have a function being called on a timer. This function continues the plot of a graph each time it is called. I am trying the HOLD('ON') command, but this overlaps my graph and does not continue from where the graph was previously plotted from. In short, my issue is continuing the plot from its previous position, and shifting my current plot by the length of the timer calls. Thus, it represents some sort of real-time monitor. The issues I need help with involve: 1) sending into the func...
