Description

Returns the maximum cell value in the matrix.

Syntax

double GetMax( )

Parameters

Return

Returns the maximum cell value in the matrix (as a double).

Note that the missing values in the matrix are excluded from the computation.

Examples

EX1

// Compute the maximum value of cells of a matrix
void matrixbase_GetMax_ex1()
{
    matrix<double> mat1 = {
        {1, 1, 1},
        {2, 3, 4}
    };
    // Output of this program will be like following:
    //   The maximum value of cells in Matrix1 is: 4 .
    
    MatrixPage MatPg1;
    MatPg1.Create("Origin");
    MatrixLayer MatLy1 = MatPg1.Layers(0);
    Matrix Mat1(MatLy1);
    Mat1 = mat1;

    double dMax;
    dMax = Mat1.GetMax();  // Compute the maximum value by GetMax
    printf("  The maximum value of cells in %s is: %g .\n",
      Mat1.GetName(), dMax);
}

EX2

// Compute the maximum value of cells of a matrix including NANUMs
void matrixbase_GetMax_ex2()
{
    matrix<double> mat1 = {
        {-1, -1,-1},
        {-2, -3,99}
    };
    mat1[1][2]=NANUM;  // set row=1,col=1 to NANUM
                // Input matrix is:
    //  {-1, -1, -1}
    //  {-2, -3  --}
    //
    // Output of this program will be like following:
    //   The maximum value of cells in Matrix1 is: -1 .
    
    MatrixPage MatPg1;
    MatPg1.Create("Origin");
    MatrixLayer MatLy1 = MatPg1.Layers(0);
    Matrix Mat1(MatLy1);
    Mat1 = mat1;

    double dMax;
    dMax = Mat1.GetMax();  // Compute the maximum value by GetMax
    printf("  The maximum value of cells in %s is: %g .\n",
      Mat1.GetName(), dMax);
