Description Usage Arguments Value Author(s) See Also Examples

Computes a generalized matrix multiplication, where sum and product functions (elemetwise and summary functions) can be replaced by arbitrary functions.

1	genMatrixMult(A,B,FUNelement="*", FUNsummary=sum)

`A`	The first matrix
`B`	The second matrix

`FUNelement`	Elementwise operator.
`FUNsummary`	Summary function.

A character vector or matrix.
