F_STBSV/F_DTBSV/F_CTBSV/F_ZTBSV

Triangular banded solve

 

 

argument incx. If incx > 0 then xi is stored in

 

 

X (1 + (i - 1) x incx). If incx < 0 then xi is stored in

 

 

X (1 + (N - i) x incx). incx = 0 is an illegal value.

Output

X

The solution vector of the triangular system replaces
