I needed to trigger a triangle pulse using a signal within my Simulink model (in my case it was a position vector). All I could find within the Sim Library was pulses set to activate at a certain time (by using a delay or building a signal from scratch). So I baked one myself.

The biggest problem was the inability to "reset" the clock (I wanted to use it as a timer to set the width of my pulse). As a substitution for the clock timer, I use switch blocks to switch between zero and integration of a constant (calculated based on pulse duration and amplitude) in order to generate the triangle pulse.
