Hi,
I have a 3D array. I would like to remove few elements (say, I want to remove all 120s in the 3D array). Once I remove them, I would like to add zeros at the end to maintain the same vector length.
Could anyone please suggest an option to do this?
Thank you so much

Here's an example with a 2x3x2 array, removing all the 9s and appending 0s:
data = reshape(1:12,[2 3 2])
data =
data(:,:,1) = 1 3 5 2 4 6 data(:,:,2) = 7 9 11 8 10 12
siz = size(data);
idx = data == 9;
data(idx) = [];
data(end+1:end+nnz(idx)) = 0;
data = reshape(data,siz)
data =
data(:,:,1) = 1 3 5 2 4 6 data(:,:,2) = 7 10 12 8 11 0
Notice the 10, 11, 12 are now in different locations. Is that what you want?
