PopIn Matlab toolbox

This toolbox was developed to plot (nano)indentation data and analyze the distribution of pop-in events.

With this Matlab toolbox, it is possible to:

• plot load-displacement curves;

• fit load-displacement curves with the Hertz model;

• plot cumulative distributions (Weibull or time- and temperature-dependent) of the first or second pop-in.
