Class:TMatrix, TIntMatrix, TMat3D
Declaration:property NrOfRows: longint;

The property NrOfRows controls the number of rows of a matrix. The matrix elements are addressed starting with an index of 1. For the classes TIntMatrix and TMatrix the properties NrOfRows and/or NrOfColumns may be set to zero to create a 0-by-0 matrix.

Hint 1: If you have to adjust not only NrOfRows but also NrOfColumns then it is faster to use the method Resize.

Hint 2: In the Light Edition the number of cells is restricted to 2000 (NrOfColumns times NrOfRows).

Example: This property is used in the following example programs (see for downloading the code): covar, findcent
