meas_slope :
A primitive for measuring the slope of an xreal-typed signal at triggering events.

The meas_slope primitive measures the slope (i.e. derivative value) of an xreal-typed signal in when it is triggered by the input trig. The real-typed output out indicates the sampled slope value of the signal at the triggering events. The output out initially takes an “NaN (not-a-number)” value until the first triggering event occurs, and gets updated to a finite value once a triggering event occurs.
