Hi all
i have a cell matrix A like that:
val(:,:,1,1,1) =
Columns 1 through 10
{n×2 double} {n×2 double} {n×2 double} {n×2 double} {n×2 double} {n×2 double} {n×2 double} {n×2 double} {n×2 double} {n×2 double}
Columns 11 through 20
{n×2 double} {n×2 double} {n×2 double} {n×2 double} {n×2 double} {n×2 double} {n×2 double} {n×2 double} {n×2 double} {n×2 double}........
i want to obtain another cell matrix with the same global dimension of the previous one but with only the first column values: so i want to obtain a matrix where each cell has dimension equal to {nx1} . I also want to estrapolate from A only those cells that contain elements with imaginary part less than 0.1 setting to zero all the cells that don't satisfy this condition. Is there an easy way for doing that?
Thank you for the help
Regards

Here is the solution to the first part
A; % 1x20 cell array
A_new = cellfun(@(x) {x(:,1)}, A);
All cell in A_new will contain first column of matrices in A.
I didn't understand the 2nd question related to setting the imaginary part to zero.

Ok. Following should work in this case
A; % 1x20 cell array
A_new1 = cellfun(@(x) {x(:,1)}, A); % only contain 1st columns
A_new2 = cellfun(@(x) {x.*(imag(x)<0.1)}, A_new1); % set the rows which does not satisfy the imaginary number conditions to 0.
