4.1.4 PWLWave

Command structure of PWLWave.

PWLWave returns a numerical value in case the first argument is numeric, otherwise a CheckedPWLWave is returned. If the last argument is not specified PWLWave returns an interpolating function object. CheckedPWLWave is a data type which marks a PWLWave description as being syntactically correct. CheckedPWLWave should not be defined directly.

A CheckedPWLWave can be displayed with standard Mathematica graphic functions such as Plot or with Analog Insydes graphic functions such as TransientPlot.

PWLWave has the following optional arguments:
