FactoredPSDMatrix.solve(rhs)[source]

Solve a linear system of equations with factor-structured coefficients.

Parameters: rhs (array-like) – A 2 dimensional array with the same number of rows as the PSD matrix represented by the class instance. C^{-1} * rhs, where C is the covariance matrix represented by this class instance.

Notes

This function exploits the factor structure for efficiency.
