## Function Svbksb-Sf

(

**svbksb-sf** < u > < w > < v > < m > < n > < b > < x > &optional < tmp > )

Solves A X = B for a vector ` X,' where A is specified by the mxn array U, `

n'

vector W, and nxn matrix V as returned by svdcmp. ` m' and `

n' are the

dimensions of ` A,' and will be equal for square matrices. `

B' is the 1xm input

vector for the right-hand side. ` X' is the 1xn output solution vector. All<br> arrays are of single-floats. No input quantities are destroyed, so the routine<br> may be called sequentially with different B's. See the discussion in Numerical<br> Recipes in C, section 2.6.<br> <br> This routine assumes that near zero singular values have already been zeroed.<br> It returns no values, storing the result in `

X.' It does use some auxiliary

storage, which can be passed in as ` tmp,' a single-float array of length `

n,' if

you want to avoid consing.
