As an engineer I typically do a lot of work with matrices and oftentimes symbolic matrices. I might generate a symbolic matrix and perform some computations that creates a function of the symbolic elements of the matrix. I now want to turn those symbolic expressions into a procedure that is a function of the matrix array input. How can this be done? There does not appear to be any simple solution. This task is so obvious and so common that I'm shocked there is no simple answer. Here is a trivial example The symbolic matrix with( LinearAlgebra) : U := Matrix(2,2, symbol=u) ;
