Robust MatLAB function for nonlinear-inelastic time-history analysis of SDOF oscillator subjected to multi-axial simultaneous excitation including horizontal, vertical and rotational motions. It also computes components of seismic input energy imparted to SDOF oscillator.
The main features are:

- Multi-axial excitation
- Material nonlinearity is presented by Ozdemir's rate-independent force-displacement model
- P-Delta (global level) is included
- Absolute and relative energy components computation

Syntax: nonlinearSDOFmultiAxial
