x = 0:50;y = 0:20;[X,Y] = ndgrid(x,y);XY = [X(:), Y(:)];R=5;AB=[((X(:)-25).^2 + (Y(:)-10).^2).^0.5];Displacement = permute(reshape(AB.',(compwidth+1),(compdepth+1),[]),[2 1 3])-R
How can I change the values of the matrix which meet certain condition into another specific number for further calculation?
if Displacement(:,:)<=0 %that specific value become 0
else %values remain unchange
end
