i am doing a project where i need to process different images and plot the highest intensity points.

for that i defined x as the number of images (which are 250),y as 640(as the image is 640 by 480)and scan all the 480 pixels for a given y and note it as v(y,x)=the other coordinate of the pixel(one of them is y)

now,while plotting a mesh,when i use the following command,
i get a mesh.

but in case i use the following command




but as soon as i write the third command,an error is displayed which says given value exceeds matrix dimensions.

Can u please tell me why im getting the error and how i could avoid it?

Thanks a lot

Hi Varun,

You should instead use something like this:

[X,Y] = meshgrid(1:250,1:600);
