1/ lu factors of a sparse matrix A are obtained through:
|
|
|
represents a space character.
Enter a space in the equivalent position in the translation.

|
|
lup = umf_lufact(A)
lup is a pointer to the lu factors (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.
|
|
|
|
lup = umf_lufact(A)
lup は LU分解へのポインタです (そのメモリはScilab空間の外です)

x = umf_lusolve(lup,b)
or x = umf_lusolve(lup,b,Ax=b,A) to add an iterative refinement step
|
|
|
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.
|

|
x = umf_lusolve(lup,b)
または x = umf_lusolve(lup,b,Ax=b,A) (反復改良ステップを追加する場合)
