Example message

Array is not symmetric in system function Decompose

Cause

The indicated function, i.e., Decompose, requires its matrix parameter to be symmetric.

The Cholesky decomposition of a real matrix A is a lower triangular matrix, L, such that A = L L*, where L* is the transpose of L. This decomposition exists only when A is symmetric - meaning that A is equal to its transpose. When you pass a non-symmetric matrix to Decompose, you get this error.

Remedy

Pass a symmetric matrix as an input parameter to Decompose.
