Hi,

I have a matrix (called Ebin2) that represents a light field. First I would like to save it on my desktop and I have done:

filename = 'path\MatriceCentri.mat';
save( filename, 'Ebin2' );

when i want to visualize this Ebin2 I can write figure,imagesc(Ebin2(:,:)) and it works.

If I want to open it, for example in another programme, I have tried with load and then

figure,imagesc('name')

But I have errors.

How can I open a mat and visualize it with figure,imagesc()?

How are you loading the .mat file. If you load it by double clicking, then following should work

figure,imagesc(Ebin2)

If you want to load it programmatically, then try this

filename = 'path\MatriceCentri.mat';
data = load(filename);
figure,imagesc(data.Ebin2)
