Using Piecewise Linear Functions in Expressions

The following piecewise linear intrinsic functions are accepted in expressions:

pwl (dataset_expression, variable)

pwl_periodic (dataset_expression, variable)

The pwl function interpolates along the x-axis and returns a corresponding y value. The pwl_periodic function also interpolates along the x-axis but periodically.
