I am working on a problem where it is convenient to compute a continuous signal based on a mathematical function and play it for a period of time T. Once T has elapsed, I would like to change parameters of the signal and begin again.
An example would be y(t)=c1+c2*(t-kT)+c3*(t-kT)^2. This would resemble a bunch of parabolas or lines concatenated together at every sample period T (the derivative is not necessarily continuous at kT). I would like to be able to set c1, c2, and c3 to different values that are calculated by a separate algorithm at each time step.
In the past I have set it up as a dynamic system and used various techniques to set initial conditions of integrator boxes, etc to get what I want. This works, but is somewhat rube-goldberg and I'd like to see if anyone has a more elegant solution. Does something like this already exist in the toolbox that I am unaware of?
What I'd like is a box where I can set the mathematical function with inputs for c1,c2,c3, etc and a continuous output. Whenever c1,c2,c3 are changed, I'd like the function to start over (there might be a separate trigger or clock input). I do realize I could probably make my own such box, but I'm thinking there must be a more elegant way.
