OpenEuphoria

Does Euphoria need a set of matrix operations? That is, operations that use a matrix construct.

And if so, should they be built-in or can they be in a library?

By matrix I'm referring to a two-dimensional array of data, one that has 0 or more rows or elements and each row is the same size. It could be represented as a sequence containing sub-sequences all of the same length. eg.

sequence mat 
 
mat =  
 { 
  {1,2,3}, 
  {4,5,6}, 
  {7,8,9} 
 }
