MXDOT2 mat1 mat2 mat3
Takes the “dot product” of matrices mat2.ufm and mat1.ufm together to produce an output file mat 3.ufm; i.e.:
I.e., each cell element in matrix 1 is multiplied by the corresponding cell in matrix 2 so that if, say, matrix 1 is a trip matrix (pcus/hr) and matrix 2 is a skimmed time matrix (hrs) then the resultant matrix is a matrix of pcu-hrs/hr.
N.B. This is not the normal mathematical definition of matrix multiplication but one that is probably far more commonly used by network modellers.
