Function list: TVec

TVec object function list

TVec object:

All listed functions support: real and complex numbers (where appropriate). Most functions are overloaded, to minimize the number of parameters required.

The class is derived from TDenseMtxVec.

For comprehensive help file please see the online documentation of MtxVec for Delphi/C++ Builder or MtxVec for Visual Studio .NET
