how to make this function periodic in MATLAB?

I have wrote this code in MATLAB editor and want this function to be periodic (period = 0.8s)

HR=75;

E_max=2.0;

E_min=0.06;

t_c=60/HR;

T_max=0.2+0.15*t_c;

t=0:0.0001:t_c;

t_n=t/T_max;

E_n=1.55*(((t_n/0.7).^1.9)./(1+(t_n/0.7).^1.9)).*(1./(1+(t_n/1.17).^21.9));

E=(E_max-E_min)*E_n+E_min;

plot(t,E)

I want to use the function in simulink as a voltage source. so i do not need a point but the whole function. so I need a function that takes the overall time (for example 20 secs) and gives the output CONTINUSELY (like a Sin function).

the function and it's shape is: http://tinypic.com/r/2641a1s/8

Solution

  • Create your data in the MATLAB base workspace by running your code in MATLAB before running your Simulink model. Then use the Repeating Sequence Block. Use your variable t as the Time Values and E as the Output Values. You'll also need to make sure that the maximum step size that the solver takes is min(diff(t)), which in the case of your data is 0.0001.
