- class riptable.rt_imatrix.IMatrix(ds, dtype=None, order='F', colnames=None)
Experimental class designed to take a Dataset and make a 2d matrix efficiently. It uses rt.vstack order=’F’ which uses rt.hstack plus np.reshape.
The matrix is shaped so that it can be inserted back into the Dataset.
- Parameters:
dtype –
order –
colnames –
