How can I eliminate the following error?

I am trying to read multiple images in order to generate a movie in Matlab. So, I use this code:
M = zeros(1,10);
for i = 1:10
images = sprintf('img%d.jpg',i);
ImageData = imread(images);
M(i) = im2frame(ImageData);
end
movie(M)
movie2avi(M,'sonar.avi','compression','None','fps',6,'quality',100)
But I get the following error:
"The following error occurred converting from struct to double:
Error using double
Conversion to double from struct is not possible.
Error in open83B_edited_2 (line 295)
M(i) = im2frame(ImageData);"
Could you please help me in seeing where is the error in my code? Thank you.

The problem comes in when you are defining your M as an array of doubles before the loop. I would make sure there exists no M in the workspace or use
clear M
in place of the current M = zeros(1,10);.
The im2frame function passes a structure so M needs to be an array of structures and not doubles.

Below is the code snippet for svmtrain.m :
if plotflag
hSV = svmplotsvs(hAxis,hLines,groupString,svm_struct);
svm_struct.FigureHandles = {hAxis,hLines,hSV};
end
here, plotflag is false and following error occurs: The following error occurred converting from struct to double:
Error using double
Conversion to double from struct is not possible.
I tried to make plotflag=true but still same error occurs.
Please advise.

@Astha Ameta: If plotflag is false then the code you have shown us does not get executed, and so cannot be the cause of this error. If you want help, you should show us the code where the error happens, not some different code.
Also please show us the complete error message. This means all of the red text.

How can I remove this error?
close all;
figure(1);
subplot(211);
plot(t,qd(:,1),'k',t,q(:,1),'r:','linewidth',2);
xlabel('time(s)');ylabel('Position tracking of link 1');
legend('Ideal position signal','Tracking position signal');
subplot(212);
plot(t,qd(:,2),'k',t,q(:,2),'r:','linewidth',2);
xlabel('time(s)');ylabel('Speed tracking of link 1');
legend('Ideal speed signal','Tracking speed signal');
??? Error using ==> plot
Conversion to double from struct is not possible.
