| Method Summary | |
| public static double[] | solve(double[][] a, double[] b)
Solves a system of equations using Gaussian Elimination. |
| solve | | public static double[] solve(double[][] a, double[] b)(Code) | | Solves a system of equations using Gaussian Elimination.
In order to avoid overhead the algorithm runs in-place
on A - if A should not be modified the client must supply a copy.
Parameters:
a - an nxn matrix in row/column order )modified by this method)
Parameters:
b - a vector of length n a vector containing the solution (if any) null if the system has no or no unique solution
throws:
IllegalArgumentException - if the matrix is the wrong size |
