I have a mat file and its size is 1243x1182x3 . (please note that size of the Mat file is NOT consistent and there are about 50-60 MAT files in one folder). And i want to add an extra column to the Mat file? (columns in the matrix are x and y columns. And my requirement is to add a 3rd column which is z column to the matrix) I guess i can do two things:
- Use save(filename, ..., '-append')But the class of my MAT file is uint8. But the examples i have seen were in the class Double.
- Or else i have to write it in a cell array
for n=1:10
A=rand(5);
[i,j,vals]=find(A);
data={[i,j,vals]};
save('data','data','-append');
end
As size of these MAT files are inconsistent and they are in RGB file formats hence i am not sure how to tackle this matter.
Can anyone kindly guide me to resolve this issue?

The x and y values returned from the find(any(Data,3)) will never be 0.

xyz = [x, y];
xyz(:,3) = SliceThickness;
save('P3290190.mat', 'xyz', '-append')
