Operating System:XP

Hi,
a good way to copy a big matrix with OriginC seems to be the following:

void matrix_copy()
{
MatrixLayer mat;
MatrixLayer matSource("mymatrix");
int nOption = CREATE_VISIBLE_SAME;
BOOL bRet = mat.CreateCopy(matSource, nOption);
}

After each execution a new copy of "mymatrix" is generated in an new window, having a new name (mymatrixN, where N is an integer increment number).

Here's my problem:
Is it possible to change the code, so that the copy is always generated in an already existing window without channging its name?

Thanks for any help

Stefan

Hi,
I found the following solution:

void matrix_copy()
{
MatrixLayer matdelete("Results");
matdelete.Destroy();
//deletes matrix "Results" first if there is any!
MatrixLayer mat("newmat");
MatrixLayer matSource("Matrix1");
int nOption = CREATE_VISIBLE_SAME;
BOOL bRet = mat.CreateCopy(matSource, nOption);
mat.GetPage().Rename("Results");
//renames matrix "newmat" to "Results".
}

bye

Stefan

Hi Stefan,

Here is an alternative method that doesn't involve destroying and recreating the Results matrix...

void matrix_copy(string sMatName)
{
	Matrix m1(sMatName);
	if( !m1 )
		return;
	uint nCols = m1.GetNumCols();
	uint nRows = m1.GetNumRows();
	MatrixPage mp("Results");
	if( !mp )
	{
		mp.Create("Origin.otm");
		mp.Rename("Results");
	}
	Matrix m2("Results");
	m2.SetSize(nRows,nCols);	
	m2 = m1;
}
