matrix addition

[#DOMINIC DENVER JOHN CHANDAR#]

How about MatAXPY() ?

manualpages/Mat/MatAXPY.html

 Computes Y = aX + Y , where X, Y are matrices. Set a=1.

Subject: matrix addition

Hi,
   I need to add two matrices, but I did not find a direct function to
do so. Is there a specific reason not having a matrix addition function?
   In the absence of such a function, I am thinking of extracting each
row of the two matrices and adding them. Would there be a more efficient
way to do the same?

   Kindly help me with your advice.

Thanks,
Manav
