1/ the Cholesky factorization of a s.p.d. matrix A is obtained with:
|
|

represents a space character.
Enter a space in the equivalent position in the translation.

Cp is a pointer to the Cholesky fact. (the memory is outside scilab space) 
|
|
|
represents a line break.
Start a new line in the equivalent position in the translation.
|
|
|
represents a space character.
Enter a space in the equivalent position in the translation.
