FLOWMath

A collection of mathematical functions and convenience methods. These are simple methods we use regularly in our lab that aren't readily available in the Julia ecosystem.

Authors: Andrew Ning and Taylor McDonnell

Quadrature

• trapezoidal integration

Root Finding

• Brent's method

Interpolation

• Akima spline
• linear interpolation
• 2D/3D/4D interpolation from recursive 1D iterpolation

Smoothing

• absolute value
• Kreisselmeier-Steinhauser constraint aggregation function
• sigmoid blending
• cubic/quintic polynomial blending

Complex step safe versions of

• abs: abs_cs_safe
• abs2: abs2_cs_safe
• norm: norm_cs_safe
• dot: dot_cs_safe
• atan (two argument form): atan_cs_safe
