| void Fit::Jordan | ( | std::vector< realt > & | A, | |
| std::vector< realt > & | b, | |||
| int | n | |||
| ) |
This function solves a set of linear algebraic equations using Jordan elimination with partial pivoting.
A * x = b
A is n x n matrix, realt A[n*n] b is vector b[n], Function returns vector x[] in b[], and 1-matrix in A[]. return value: true=OK, false=singular matrix with special exception: if i'th row, i'th column and i'th element in b all contains zeros, it's just ignored,
