Detailed Description

Provides functions for linear algebra operations on psImages and psVectors.

Functions are provided to: Transpose a psImage Compute LUD Solve LUD Matrix inversion Calculate determinant Matrix multiplication Calculate Eigenvectors Convert matrix to vector Convert vector to matrix

These functions treat psImages as if they were matrices, therefore there is no psMatrix. These functions operate only with the psF64 data type.
