Pre-processor for the routine
This routine is called from
?gesvjas a pre-processor and that is its main purpose. It applies Jacobi rotations in the same way as
?gesvjdoes, but it does not check convergence (stopping criterion).
?gesvjto use a simplified version of itself to work on a submatrix of the original matrix.
- CHARACTER*1. Must be'V','A', or'N'.Specifies whether the output from this routine is used to compute the matrixV.If, the product of the Jacobi rotations is accumulated by post-multiplying thejobv='V'n-by-narrayv.If, the product of the Jacobi rotations is accumulated by post-multiplying thejobv='A'mv-by-narrayv.If, the Jacobi rotations are not accumulated.jobv='N'
- INTEGER. The number of rows of the input matrixA(m≥0).
- INTEGER. The number of columns of the input matrixB(m≥n≥0).
