Thanks Viktor.
This work directly in Maxima or in batch file but not in translated code.
The translated code is :
(MFUNCTION-CALL $LENGTH (MAREF $MAT 1))
> De : Viktor T. Toth [mailto:vttoth@vttoth.com]
> Try length(a[1]).
> The difference is that row(a,1) returns a matrix (of one row), while a[1]
> returns a list.
