Loop with error "This value must be a matrix"

[mstoehr-2]

Hello,

I hope, this is the right thread.

Could someone explain me, what I have to do with this loop.

I want to get F as a (3,4) Matrix.

Thank you for helping ...

The offending statement:

Is assigning f to u, rather than to the element on row v and coumn u of F. I guess it should be :

Then you have a funny index '.q.v' for M in the row above.

Can you post the worksheet?

You're right Luc, I haven't seen it

Thank you.

M.q.v ist a literal index q for M with a field index v. Do you see any problem with it?

But everything seem workings right now.

Not immediately. If it works it works...

Apparenly you have a Matrix M, 3x4 elements,

and a Vector M..q, of 4 elements.
