Examples of org.apache.commons.math.linear.RealMatrixImpl.solve()

org.apache.commons.math.linear.RealMatrixImpl.solve()
Returns a matrix of (column) solution vectors for linear systems with coefficient matrix = this and constant vectors = columns of b. @param b array of constant forming RHS of linear systems toto solve @return solution array @throws IllegalArgumentException if this.rowDimension != row dimension @throws InvalidMatrixException if this matrix is not square or is singular

            }


            try {


                // solve the linearized least squares problem
                RealMatrix dX = a.solve(b);


                // update the estimated parameters
                for (int i = 0; i < parameters.length; ++i) {
                    parameters[i].setEstimate(parameters[i].getEstimate() + dX.getEntry(i, 0));
                }
