`make-matrix-map:`procedureGiven procedures

`VECTOR-REF`and`FILL-MATRIX!`, returns a procedure`MATRIX-MAP`of the form`MATRIX-MAP:: M * N * A * F * [IX * IY * EX * EY] -> B`Where procedure

`MATRIX-MAP`applies the map operation on a matrix`A`of size`M x N`with the values returned by applying procedure`F`to each pair of indices and the corresponding value at that position in the matrix.Procedure

`F`is of the form`LAMBDA I J V -> U`, where`V`is a matrix element at position`(I,J)`and`U`is corresponding element in the return matrix.Optional arguments

`IX IY EX EY`may specify a sub-matrix in matrix`A`.`VECTOR-REF`is one of the homogeneous vector accessor procedures from SRFI-4.
