Matrix inversion

 

For AX=Y, if the inverse matrix of A exists, the system of equations can be solved by inverse method

..

SPL code:

A

1

[[1,2],[2,3]]

2

[8,13]

3

=inverse(A1)

4

=mul(A3,A2)

A1 Input the coefficient matrix

A2 Input Y

A3 Inverse A1

A4 Multiply the A3 and A2 matrices, return
