Question
Hi, i am trying to generate a periodic decaying exponential signal in the time interval between -5 and 100 . I am trying to visualize it like a sawtooth waveform (but reversed and having gradual decay). can someone help me with this t=-5:t_step:100; bt_new=0; L=0.018; t_step=0.1221; N= L/t_step; for l=0:2.0930e-03:N bt = exp(-0.24*((t-(l.*ones(size(t))*t_step)))); bt_new =bt_new+bt; end plot (t,bt_new); I am trying to generate a periodic decaying exponential, any ideas

is this close to what you want?
clear;clc t = -5:.1:100; plot(t,fliplr(sawtooth(t)).*exp(-t./20))
