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.

Value

A vector or a (traditional numeric) matrix with the result of the matrix product.

Arguments

x

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