This question has already been answered? I searched but I didn't find it
thank you very much for your answer but I mean we have a matrix nbym: assume M= [a b c;d e f; g h i] I want to interpolate its rows so that is equal to M=[a a+d a+2d a+3d ... 7d b b+d ... b+7d c... c+7d ; d... d+7d... f+7d ; g ... i+7d] Can you explain me how I could do it?
