NrOfColumns

Declaration: TMat4D.NrOfColumns: integer;
The property NrOfColumns controls the number of columns of the hypercube matrix. The matrix elements are addressed starting with an index of 1.

Hint: If you have to adjust not only NrOfColumns but any of the other dimensions (NrOfRows, NrOfLayers, or NrOfTimeSlots) as well, then it is faster to use the method Resize.
