matrix programming ... - jtamezga - 04-18-2020 06:06 PM
It is possible to program or create an empty matrix when i´m trying to request first time data? ... i´m using this commands, but it's necessary to put some initial values (ceros in this case) when i establish number of columns (and rows) in stack view:
EXPORT Destats()
BEGIN
LOCAL mat,var;
var:=Ans(1);
mat:=MAKEMAT(0,var,var);
mat:=EDITMAT(mat);
END;
Best regards ... JT

Every element of a matrix has to have some value in it. Zero is as good a starting place as any, no?
