◆ deriv()

template<class Vec>
virtual Vec GIMLI::TransLinear< Vec >::deriv ( const Vec & x) const
inlinevirtual

Return $ a = \frac{\partial}{\partial x} (b + a * x) $

Reimplemented from GIMLI::Trans< Vec >.

◆ invTrans()

template<class Vec>
virtual Vec GIMLI::TransLinear< Vec >::invTrans ( const Vec & f) const
inlinevirtual

Return $ x(f) = (f - b)/a $

Reimplemented from GIMLI::Trans< Vec >.

◆ trans()

template<class Vec>
virtual Vec GIMLI::TransLinear< Vec >::trans ( const Vec & x) const
inlinevirtual

Return $ f(x) = b + a \cdot x $.

Reimplemented from GIMLI::Trans< Vec >.
