Member Function Documentation

virtual Shape jive::model::ImplicitMatrix::shape ( ) const

virtual

Returns the shape of this matrix. If s denotes the returned Shape object, then s[0] equals the number of rows and s[1] equals the number of columns in this matrix.

Returns

The shape of this matrix.

Implements jive::algebra::AbstractMatrix.

virtual void jive::model::ImplicitMatrix::matmul ( const Vector &  lhs, const Vector &  rhs  ) const

virtual

Multiplies the vector rhs with this matrix and stores the result in the vector lhs. The sizes of the two vectors must be compatible with the shape of this matrix.

Parameters

lhs	- the result vector.
rhs	- the vector to be multiplied by this matrix.

Precondition

lhs.size() == shape()[0] &&
rhs.size() == shape()[1]

Implements jive::algebra::AbstractMatrix.
