MatMult: MatMult: Specialized matrix multiplication of DMat, ShrnkMat, ShrnkMatInv, SigFq and SigFqInv objects.

Description

LeftMult multiplies, on the left, a vector or matrix of compatible dimensions, by a DMat, ShrnkMat, ShrnkMatInv, SigFq or SigFqInv object.

RightMult multiplies, on the right, a vector or matrix of compatible dimensions, by a DMat, ShrnkMat, ShrnkMatInv, SigFq or SigFqInv object.

Arguments

x

An object of class DMat, ShrnkMat, ShrnkMatInv, SigFq or class SigFqInv, with a compact representation of a specialized square symmetric matrix.
