Elem

Declaration:	TMat4D.Elem [ix,iy,iz,it: longint]: double;
The property Elem is used to access a specific cell of the four dimensional matrix. The parameters ix, iy, iz, and it specify the indices (columns, rows, layers, time slots) of the element to be accessed (starting with an index of 1). If any of the indices is invalid, Elem returns 0.0 (in case of a read operation), or the assignment is ignored (in case of a write operation).
