Matrix definition

[jlaybar]

Matrix a1 = Col(1,-1,0,0,0,0);
-----------------------------------------------------
Matrix a2 = ((1,-1,0,0,0,0)); Don´t work
---------------------------------------------

Matrix a3 = ((1,0),(0,1)); Work

The problem isn't the sentence declaration based on two parenthesis. The problem
appears when we use negative values under that form. You can try it with:

Matrix a2 = ((1,2,3,4));

It works, but if some of those values were negative, the error appears.

I have accepted the error. I tell you something soon.

This bug has just been resolved.
The problem was a bad interpretation of the lenght of syntactical tree received
as argument in EvaluateMatrix function of graimp.cpp.

Matrix a = ((1,1)); this works
Matrix b = ((1,-1)); Also this works
Matrix c = ((1,-1),(-1,1)); and this works too
Matrix d = ((3)); but this doesn't work because it considered a Real
Instead of last form, use this other:
Matrix d = Col(3);

Tschüss!
