R is a numeric scalar, vector or matrix. If R is a matrix, ≥/⍴R must be true. | ||||
Z is a numeric array of rank ⍴⍴R, and shape ⌽⍴R. |
This feature implements matrix inversion using Singular Value Decomposition. In particular, this means that any numeric array meeting the rank and shape requirements above is invertible.
For example,
⌹3 3⍴0
0 0 0
0 0 0
0 0 0
