I have a 5x9 cell array A. Each cell in A contains a 3x1 cell. In each cells, I have mesh data for a surface. For example A{1,1} have three 119x755 matrix in each cell. But the mesh matrix size in A{1,2} are not in the same size of A{1,1}. I want to make the mesh size all the same in each cell array for example 100x700. How can I do it using cellfun?
A =
3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell
3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell
3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell
3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell
3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell 3x1 cell
A{1,1} =
119x755 double
119x755 double
119x755 double
A{1,2} =
122x764 double
122x764 double
122x764 double

Do you want to pick the first 100 x 700 entries, throwing away the information in the remaining rows and columns?
Or do you want to interpolate the data down, such as doing an imresize() operation on it?

newA = cellfun(@(C) cellfun(@(M) imresize(M, 100, 700), C, 'uniform', 0), A, 'uniform', 0);

A = {{zeros(128, 800);; zeros(128,800)}, {ones(150, 900); ones(150, 900)}};
newA = cellfun(@(C) cellfun(@(M) imresize(M, [100, 700]), C, 'uniform', 0), A, 'uniform', 0);
newA{1}
