The INVERT function uses the Gaussian elimination method to compute the inverse of a square array. The result is a single- or double-precision floating-point array. Errors from singular or near-singular arrays are accumulated in the optional Status .
The array to be inverted. Array must have two dimensions of equal size (i.e., a square array) and can be of any type except string. Note that the resulting array will be composed of single- or double-precision floating-point values, depending on whether the DOUBLE keyword is set.
A named variable to receive the status of the operation. Possible status values are: 0 for successful completion, 1 for a singular array (which indicates that the inversion is invalid), and 2 which is a warning that a small pivot element was used and that significant accuracy was probably lost.
