Specified by:

solve in interface LeastSquaresSolver

Following copied from interface: org.jutil.math.matrix.LeastSquaresSolver

Parameters:

A - The matrix containing the coefficients of the equation. Each row represents an equation. The i-th element of a row represents the coefficient of the i-th variable in the equation represented by that row.

b - The column representing the right-hand sides of the equation. The right-handig side of the i-th row is the i-th element of the Column
