2.2.3.8.9 Matrix::GetYMax

GetYMax

Description

Get the Y coordinate associated with the last row of the matrix.

Syntax

double GetYMax( )const

Parameters

Return

Returns the Y coordinate associated with the last row of the matrix.

Examples

EX1

// Set and get the Y coordinate of the last row of a matrix
void Matrix_GetYMax_ex1()
{
// This sample code will print a message like below:
//   Target matrix is Matrix1.
//   Setting Y max value succeeded.
//   Obtained Y max value is 1.23457e+008
//   Check Y max value by Matrix:Set Dimensions menu command if it is 1.234570e+008.
//
    BOOL rc;
    
    double dYMax;
    matrix<double> mat1 = {
        {1,  2},
        {3,  4},
        {5,  6}
    };

    MatrixPage MatPg1;
    MatPg1.Create("Origin");
    MatrixLayer MatLy1 = MatPg1.Layers(0);
    Matrix Mat1(MatLy1);
    Mat1 = mat1;
    printf("  Target matrix is %s.\n",Mat1.GetName());

    rc=Mat1.SetYMax(123.4567E6);  // Use SetYMax to set the Y coordinate of last row
    if(!rc) {
        printf("  Error: SetYMax failed.\n");
        return;
    }
    else printf("  Setting Y max value succeeded.\n");
    dYMax = Mat1.GetYMax();   // Use GetYMax to get the Y coordinate of last row
    printf("  Obtained Y max value is %g\n", dYMax); // Print out coordinate
    printf("  Check Y max value by Matrix:Set Dimensions menu command if it is %e.\n",dYMax);
}

Remark

In addition to the values displayed in the cells of an internal Origin matrix (nominally Z values), Origin matrices map X coordinate values to the columns and Y coordinate values to the rows of the matrix. The GetYMax function gets the Y coordinate associated with the last row of the matrix.
