How can I use a time dependent function as input source for my Simulink Model?

That is the defined function in my Matlab Function Block: The Result should be a curve the the Time t should be a interval e.g. from 0 to 10 How can I enter the time?

function i8_20 = fcn(t) %#codegen

ipeak=10000;

i8_20 = (ipeak/0.616)*sin(0.12*10^6*t)*exp.(-(t/(24.1e-06)));

You can use the clock block to get the time. http://www.mathworks.com/help/simulink/slref/clock.html

Thank you! But how can I set the time range? e.g. from 0 to 10e-6?

Thx

This depends on your stop time in model configuration parameters

[Vishnu Panchal]

My stop time is 2 sec. Now, if i make use clock block it just gives me two steps. I want to reduce its step time to 100usec. How should I do it?

you could try it with a triggered subsystem, which is triggered with a pulse generator with a period time of 100us
