New Bug in Matrix with SCALE [Solved]

Sorry about the issue.
If you need to use SCALE, doing M1:= SCALE(EVAL(M1), ....) might work better.
SCALE is part of a small but frustrating number of functions that do side effects (ie, modify their inputs, in this case M1). This makes it relatively complex to implement.
This is a leftover from the HP38G.

However, SCALE is also able to work without side effects, but for this to work, you need the input to NOT be a variable name. Hence the EVAL above.

These functions SCALE and SCALEADD are similar to the HP 50 functions RCI and RCIJ, very even used in SIMPLEX. I use RCI and RCIJ in HP 50.
What is the difference of mRow function in the HP Prime?
