LinearAlgebraUtils { public static void dotmult_inplace(ComplexDoubleMatrix A, ComplexDoubleMatrix B) { A.muli(B); }  static double[] solve22(double[][] A, double[] y); static double[] solve33(double[][] A, double[] rhs); static DoubleMatrix absMatrix(DoubleMatrix inMatrix); static double[][] absMatrix(double[][] inMatrix); static DoubleMatrix matrixPower(DoubleMatrix data, double scalar); static double[][] matrixPower(double[][] inMatrix, double scalar); static void invertChol_inplace(double[][] inMatrix); static double[][] invertChol(double[][] inMatrix); static void invertChol_inplace(DoubleMatrix inMatrix); static DoubleMatrix invertChol(DoubleMatrix inMatrix); static ComplexDoubleMatrix dotmult(ComplexDoubleMatrix A, ComplexDoubleMatrix B); static void dotmult_inplace(ComplexDoubleMatrix A, ComplexDoubleMatrix B); static void fliplr_inplace(DoubleMatrix A); static DoubleMatrix matTxmat(DoubleMatrix matrix1, DoubleMatrix matrix2); static ComplexDoubleMatrix matTxmat(ComplexDoubleMatrix matrix1, ComplexDoubleMatrix matrix2); static void wshift_inplace(DoubleMatrix inVector, int n); static DoubleMatrix wshift(DoubleMatrix inMatrix, int n); static void setdata(DoubleMatrix outMatrix, Window outWin, DoubleMatrix inMatrix, Window inWin); static void setdata(ComplexDoubleMatrix outMatrix, Window outWin, ComplexDoubleMatrix inMatrix, Window inWin); static void setdata(ComplexDoubleMatrix outMatrix, ComplexDoubleMatrix inMatrix, Window inWin); static void setdata(DoubleMatrix outMatrix, DoubleMatrix inMatrix, Window inWin); static void chol_inplace(double[][] inMatrix); static void chol_inplace(DoubleMatrix inMatrix); static void invert_inplace(double[][] inMatrix); static double[][] invert(double[][] inMatrix); static void invert_inplace(DoubleMatrix inMatrix); static DoubleMatrix invert(DoubleMatrix inMatrix); static void arrangeCholesky_inplace(DoubleMatrix inMatrix); static void arrangeCholesky_inplace(double[][] inArray);  }### Answer:
@Test public void testDotmult_inplace_JBLAS() throws Exception { ComplexDoubleMatrix A_PASCAL_22_CPLX_times2_ACTUAL = A_PASCAL_22_CPLX.dup(); LinearAlgebraUtils.dotmult_inplace(A_PASCAL_22_CPLX_times2_ACTUAL, A_PASCAL_22_CPLX); Assert.assertEquals(A_PASCAL_22_CPLX_times2_EXPECTED, A_PASCAL_22_CPLX_times2_ACTUAL); }
