TMtxVec object function list

TMtxVec object:

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

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