Computes row and column scaling factors intended to equilibrate a banded matrix and reduce its condition number.
The routine computes row and column scalings intended to equilibrate an
Aand reduce its condition number. The output array
rreturns the row scale factors and the array
cthe column scale factors. These factors are chosen to try to make the largest element in each row and column of the matrix
have absolute value 1.
?laqgbauxiliary function that uses scaling factors computed by

- The number of columns of the matrixINTEGER.A;.n≥0
- The number of subdiagonals within the band ofINTEGER.A;.kl≥0
