Linear Equations

Two types of driver routines are provided for solving systems of linear equations:
Both types of driver routines handle single or multiple right hand sides by allowing $B$ to be a vector or matrix, respectively.
Different driver routines are provided to take advantage of special properties or storage schemes of the matrix $A$, as shown in Table 2.2.
