Class MatrixVectorMult



  • public class MatrixVectorMultextends Object

    This class contains various types of matrix vector multiplcation operations for DenseMatrix64F.

    If a matrix has only one column or row then it is a vector. There are faster algorithms that can be used to multiply matrices by vectors. Strangely, even though the operations count smaller, the difference between this and a regular matrix multiply is insignificant for large matrices. The smaller matrices there is about a 40% speed improvement. In practice the speed improvement for smaller matrices is not noticeable unless 10s of millions of matrix multiplications are being performed.
