For example, try this:
% Create sample data: cube of size n.
n=3;
m = randi(9, n, n, n)
% Create output array.
output = zeros(n, n-1, n);
for z = 1 : size(m, 3)
thisPlane = m(:,:,z);
columnToRemove = z;
% Remove column by setting all elements of the column to null.
thisPlane(:, columnToRemove) = [];
% Assign narrower matrix to the zth plane of the output.
output(:,:,z) = thisPlane;
end
% Print to command window.
output
