Trouble using 3D Matrix and removerows command

for i = 1:length(land_B_acq(1,1,:))

KB=find(land_B_acq(:,5,i) > mean(land_B_acq(:,5,i))+2*std(land_B_acq(:,5,i)) & land_B_acq(:,5,i) < mean(land_B_acq(:,5,i))-2*std(land_B_acq(:,5,i)));

land_B_acq=removerows(land_B_acq, 'ind', KB);

end

KB will work fine and tell me the rows where (mean + or - 2x std) is > or < the compared value. But, when I want to save the removerows output, it takes away the 3rd dimension of the matrix and stores everything in a 2d matrix.

My programming skills are only moderate.

land_B_acq is a 24x8x3 matrix and must keep the 3rd dimension.

Thank you.
