solveFq: Solve methods for SigFq and SigFqInv objects

Description

These methods solve the equation a %*% x = b for x, where a is a covariance (or precision, i.e., the inverse of a covariance) matrix represented by a SigFq (or SigFqInv) object, and b can be either a vector or a matrix.

Usage

solve.SigFq(a, b = NULL, ...)
solve.SigFqInv(a, b = NULL, ...)

Arguments

a
An object of type SigFq or SigFqInv representing the covariance, or precision, matrix associated with a q-factor model.
b
A numeric vector or matrix giving the right-hand side(s) of the linear system. If missing, b is taken to be an identity matrix and solve will return an object representing the inverse of the matrix associated with a.
...
Further arguments passed to or from other methods.

Details

The result returned depends on the values of the arguments. When b is not NULL, both functions return a numeric vector or matrix with the solution of the system. When b is NULL, solve.SigFq returns a SigFqInv object and solve.SigFqInv returns a SigFq object.
