Function Documentation

real_type Mechatronix::minCubic2p(real_type a, real_type fa, real_type Dfa, real_type b, real_type fb, real_type Dfb)

Find the minimum of a cubic passing by 2 point and initial and initial tangent.

The minimum is searched in the interval

\[ [a,b] \]
.
Parameters

  • a – the value \( a \)

  • fa – the value \( f(a) \)

  • Dfa – the value \( f'(a) \)

  • b – the value \( b \)

  • fb – the value \( f(b) \)

  • Dfb – the value \( f'(b) \)

Returns

the minimum found
