I have a very long 1 x 4000 temperature vector, A = [a1 a2 a3 a4 a5 a6 a7 .... a4000].
I also have the hours vector T = [t1 t2 t3 t4 t5 .....t4000]. A and T are given.
Now, I wish to have a stair function, such that,
if t2<=t<t3 func = a3;...
In the stuff I am doing, I used to use "piecewise" function for small number of A and T for testing (maybe just a1 to a10). So, I can manually wrote pieces one by one. Now, I need to use the real stuff A,which is very long. I cant do this one by one anymore. So, my question is, is there a way I could make a piecewise stair function for given A and T.
Please do notice that:
- This stair function will be feed into integration later. It must be ONE function, that's why I was using "piecewise" (It works well). In other words, I do NOT use it just for plot.
- Honestly, I dont know this piecewise function will allow me to manually write that many pieces to a4000 or not.
