[L]*[D]*[U] factoring of single precision band-matrix.
[L] is lower triangular with unit main diagonal [D] is a diagonal matrix [U] is upper triangular with unit main diagonal
- Parameters
-
[in] | m | The number of rows of array A |
[in] | mah1 | the left half-bandwidth of fortran array A |
[in] | mah2 | the right half-bandwidth of fortran array A |
[in,out] | a | input as the asymmetric band matrix, [A]. On output, it contains the factors in the encoding, [L-I]+[D**-1]+[U-I], I=identity. |
