Overload List

#SignatureDescription
1TMtxVec *Tanh() const;Hyperbolic tangens.
2TMtxVec *Tanh(int Index, int Len) const;Calculate the hyperbolic tangens for calling object elements [Index]..[Index+Len-1] in-place.
3TMtxVec *Tanh(TMtxVec *X) const;Calculate the hyperbolic tangens for all X object elements and store the results in the calling object.
4TMtxVec *Tanh(TMtxVec *X, int XIndex, int Index, int Len) const;Calculate the hyperbolic tangens for X object elements [XIndex]..[XIndex+Len-1]. The results are stored in the calling object elements [Index]..[Index+Len-1].

Overload 1: TMtxVec *Tanh() const;

Hyperbolic tangens.

Remarks:

Calculate the hyperbolic tangens of all caling object elements in-place.
