Hi,

Is it possible to construct a matrix with #rows larger than 180? My script doesnt work when I try to call, and returns
" Vector operation dimension check error "

************************************
matrix MAT(201,4);

for(int jj=0; jj<4;jj++)
{
for(int ii=0; ii<201; ii++)
{
MAT[ii][jj] = ...;
}
}

Hi,

Sorry that I can not reproduce the error you mentioned with the following code. The code works fine.

void testMatrix()
{
	matrix MAT(201,4);

	for(int iCol=0; iCol<MAT.GetNumCols(); iCol++)
	{
		for(int iRow=0; iRow<MAT.GetNumRows(); iRow++)
		{
			MAT[iRow][iCol] = iRow*iCol;
			printf("MAT[%d][%d] = %f\n", iRow, iCol, MAT[iRow][iCol]);
		}
	}
}

It will be better to get your entire code to make sure what the problem is.

I see what the problem was: my dataset was erroneously only filled up to 180, when I expected 201...

Thanks anyway!

Hi,

It will be better to use the GetNumRows and GetNumCols methods to get a matrix's dimension.
