Invert(c, i, j)

Returns the inverse of matrix «c». The two index parameters, «i» and «j» specify the indexes of «c» along which the inversion is to take place and must have the same length, implying that «c» is a square matrix.

Example

Variable MatrixA :=

	i ▶
j ▼	1	2	3
a	4	1	2
b	2	5	3
c	3	2	7

Invert(MatrixA, i, j) →

	i ▶
j ▼	1	2	3
a	0.326	-0.034	-0.079
b	-0.056	0.247	-0.090
c	-0.124	-0.056	0.202
