clc
clear all
close all
sf=50;
time=60;
mag=1;
S=zeros(1,sf*time);
for iT=1:length(S)
S(iT)=-mag+2*rand*mag;
end
where sf is your sample frequency, time is your time, and mag is your magnitude. S is the signal.

I want for example to generate random Power magnitudes for 2 hours time duration. So I can get at time equal 4 min. and 30 second the power is equal 50 Watt (for example)...........Is this work ?? and what is iT referring to ???

so you change your time to 7200, your mag to 50. you might want to change mag+2*rand*mag to just rand*mag since you are talking about power. if you want to look what the power was at that time you simply do: S(4.5*60).

There are many random function that you may use, such as randperm, randi and so on. Can you explore more what you want to implement?
