hello
simply turn your main code into a function a call it 100 times in a for loop
clc
clearvars
close all
ti = 0;
tf = 70E-8;
tspan=[ti tf];
% I want to plot this for 100 times for different initial condition and combine all the plots in a single
% plot.
for ci = 1:100
[T,L,r] = main(tspan);

plot(T,L,'linewidth',1.5);
