how to sample time of input vector in matlabb script

Dear all, Ihave an optimization algorithm function (MPPT) the algorithm function receive input vector, i want to sample the time between inputs like i do in simulink by insurting zero order hold block(attached in photo) but in code how to do it ? what is its effect on the overal system in terms of efficiency, speed and especially stability?

hello

most of your simulink file works with discrete signals (after the ZOH)

if you define signals as arrays in matlab with appropriate sample rate and lenght , it's like working on sampled signals in Simulink

as soon as your matlab script does the same job as your simulink file , there should be no differences at the end

in simulink i can slow the process of input by changing sample time i want to know how to do it in matlab in order to introduce an inner loop that has big responce time

in matlab you can also play with sample times , you can reduce it with decimate , resample , interp1
