element-wise matrix operations

Folks, Is there a way to cause matrix operations to be performed element by element? For example if two matrices are multiplied, the top-left element of the multiplicand would be multiplied by the top-left element of the multiplier and placed in the top-left element of the product, and so on. In mathcad this can be done by pressing <ctrl> - (vectorize).
Thanks, Jack

Hello,
No, there is no element-wise matrix operations in Smath (like vectorize in Mathcad). You just have to use loops (for, while) to perform such operations.

Ok, thanks for the quick response. Is it possible to add operators via the plugin mechanism or would that require a change to the core? The reason I am interested in this functionality is that I use it heavily in Mathcad to perform similar calculations on a set of variables. The for loop provides a similar functionality, but the visual presentation is much more awkward, unless I am missing something. By the way, this is one of the best and most needed free software I have come across. Thanks, Jack Edited by user 23 October 2010 04:49:05(UTC)
