---|
| 17 | C -------- |
---|
| 18 | C |
---|
| 19 | c This routine loads the longwave matrix of factors Ksi, |
---|
| 20 | c used to build the Net Exchange Rates matrix Psi. |
---|
| 21 | c Psi(i,j,nu) = Ksi(i,j,nu) * ( B(i,nu)-B(j,nu) ) |
---|
| 22 | c |
---|
| 23 | c This Ksi matrix has been computed by Vincent Eymet |
---|
| 24 | C |
---|
| 25 | c The NER matrix is then integrated in frequency, and the output |
---|
| 26 | c are calculated. |
