pyva.data.matrixClasses.linearIndex(N, irow, icol, btriu=True)

Provides the linear index of triangular matrices

Parameters:

• N (int) – Number of columns.

• irow (int) – row index.

• icol (int) – column .

• btriu (bool, optional) – switch for upper triangular index. The default is True.

Raises:

IndexError – Wenn btriu = False the lower triangle is used, which is only possible when the matrix is quadratic.

Returns:

linear index in upper triangula matrix.

Return type:

int
