solve:
Syntax: solve ( A , B )
solve ( A , B , TYPE )
Description:
Solve solves a system of linear equations:
A * X = B, A is the coefficient matrix
B is the right hand side
X is the solution
where A is the 1st, and B is the 2nd argument to solve(). The
columns of B are the individual right hand sides.
Solve returns a matrix of the solutions, where each column
of the solution corresponds to a column of B.
Solve uses the LAPACK subroutines DGETRF, and ZGETRF if A is
general.
Solve uses the LAPACK subroutines DSYTRF, and ZHETRF if A is
symmetric.
The third and optional argument allows the user to overide the
symmetry check, and force the solve to use either the general
or the symmetric solver.
TYPE = "g" or "G" The general solution is used.
TYPE = "s" or "S" the symmetric solution is used.
