General rectangular matrix with disk storage.
| integer function dmopen::adjustswapsize | ( | integer, intent(in) | nTot, |
| integer, intent(in) | nSwap | ||
| ) |
Adjusts the number of matrix columns in a swap section.
| [in] | nTot | Total number of matrix columns |
| [in] | nSwap | Number of swap sections |
The number of columns is set such that the total number of columns in the matrix is nearly divisable by the number of swap columns, and such that the last swap section is as close in size as possisble to the other sections.
