Description

It sets a matrix data into the data referred to by the DataRange object.

Syntax

BOOL SetData( const matrixbase & m, int index = 0, BOOL bUndo = FALSE, DWORD dwDRSOpts = 0 )

BOOL SetData( vectorbase & pv, BOOL bUndo = FALSE, int index = 0, DWORD dwDRSOpts = 0 )

BOOL SetData( vector * pvY, vector * pvX, BOOL bUndo = FALSE, int index = 0 )

BOOL SetData( vector * pvZ, vector * pvY, vector * pvX, BOOL bUndo = FALSE, int index = 0 )

Parameters

m: [input]the source data
index: [input]data index in case DataRange refers to multiple matrices.
bUndo: [input]whether the action should be undoable.
dwDRSOpts: [input] possible values:; DRS_COMPLEX - to set complex (if m is complex)

pv: [input]The data want to set into data range.
bUndo: [input]whether the action should be undoable.
index: [input]data index
dwDRSOpts: [input] possible values:; DRS_COMPLEX - to set complex (if m is complex)

pvY: [input]
pvX: [input]
bUndo: [input]whether the action should be undoable.
index: [input]data index

pvZ: [input]
pvY: [input]
pvX: [input]
bUndo: [input]whether the action should be undoable.
index: [input]data index

Return

TRUE if success.

True if Successful

Examples

EX1

// For this example to run, have two matrices, MBook1 and MBook2, and put some data
// into MBook1.
// The sample will transfer the data from MBook1 to MBook2.

    Matrix mat("MBook1");

        return;
    
    string strRangeSet = "[MBook2]MSheet1!1";
    DataRange drSet;
    int nn = drSet.AddInput(strRangeSet);
    if (nn < 0)
        return;        // failed. Perhaps Matrix2 does not exist.
    
    BOOL nRet = drSet.SetData(mat);
    out_int("nRet = ", nRet);
    
    return;
}

EX2
