genMatrixMult {blockmodeling} | R Documentation |
Computes a generalized matrix multiplication, where sum and product functions (elemet-wise and summary functions) can be replaced by arbitrary functions.
genMatrixMult(A, B, FUNelement = "*", FUNsummary = sum)
A |
The first matrix. |
B |
The second matrix. |
FUNelement |
Element-wise operator. |
FUNsummary |
Summary function. |
A character vector or matrix.
