For the following script, the subplots/plots are going behind the tab, when executed. How can this be fixed? h.mainfig = figure(); h.tabgroup = uitabgroup(h.mainfig, 'Position', [.05 .1 .9 .8]); ntabs = 4; for ii = 1:ntabs h.tab(ii) = uitab(h.tabgroup, 'Title', sprintf('Tab_%i', ii)); for jj=1:2 ax(jj)=subplot(2,1,jj);plot(1:10,sin(1:10)); end linkaxes(ax,'x'); end ...

I'm trying to change panel and axes width and height values by using user input. These values will represent a photograph's resolution. For example, if a user inputs 512*512, the uipanel and Axes' width and height will change to 512 and the user will work on this workspace. What I...

I have a matlab function that contain some constant parameter, I want to draw that function, on say same figure, using hold on (probably) while changing the value of that constant. This my code: close all clear all clc m = 5; x = 1:1:10; y = m*x + 10;...

Pest = gridfit(ke, ks, S.totDis, ke_pts, ks_pts); imagesc(Pest) colorbar; xlabel('k_e'); ylabel('k_s'); I wish that the scale of the axis be the values of data instead of the data point indexes. This might be naive. I am new to matlab, please help. Edit: I wish the y-axis to be increasing instead...

I have a saved matlab .fig file which has an image and I open the fig using openfig. I'm asking how I can copy the figure values in a matrix (lets say img which is 480x640 double)to start doing some processing on it. If anyone could please advise.

For some reason, I would like to plot the line and marker of the same data separately. data1 = (1:1:10)'; data2 = (1:2:10); figure(1); plot(data1,data1,'or'); hold on; plot(data2,data2,'-r'); legend('data'); However it will only display the legend for the first plot. And Matlab seems not to have option to manipulate the...

I'm struggling to plot multiple functions on one figure. Here is the code that I have: syms t a; a=0.9514; F1=0.5*sqrt(3*t^2); F2=-0.28375*t^2+1.155*a*(t-a)+1; F3=1; E1=diff(F1,t); E2=diff(F2,t); E3=diff(F3,t); I want to plot E1, E2 and E3, each only within a certain range, to make a "composite" line. I've tried plotting with ezplot...

I am trying to obtain very nice plots for my presentation below is a code that I used to plot clear all clc close all syms v omegat= -2:0.000001:2; Nt=32; gainfuc = (1/Nt)*exp(1i*pi*omegat*(Nt-1)/2).*sin(pi*Nt*omegat/2)./sin(pi*omegat/2); gainfuc(omegat == 0) = 1; G = (omegat < 2/Nt).*(omegat > -2/Nt); plot(omegat,abs(gainfuc)) syms t hold on...

My MATLAB script generates a figure from a timeseries data that, when saved, is over 200 MB in size. Is there a way to compress the figure to a lesser size in '*.fig' format? The compression has to be lossless so that I can zoom in and view the details...
