Library Functions -- $%MTXEQU^MATH


This function either solves a matrix equation and returns the value of the determinant of the matrix, or returns an empty value to indicate that no matrix can be computed to solve the equation.

The matrix equation to be resolved is [A] * [Result] = [B].

Assuming that the matrixes A and B contain:

       A                  B
4   2   3   1         2   1   0
1   2   3   4         1   4  0.5
3   4   1   2         2   3   0
2   1   3   4         0   0   1

then the function call SET X=$%MTXEQU^MATH(.A,.B,.R,4,3) would return the value -60 in X and return as matrix R:

0.21666  -1.85   0.20833
0.78333   2.15   0.29166
0.61666   1.65   0.20833
0.55      0.85   0.375
