Matlab Function, switch case Problem
显示 更早的评论
I am writing a Matlab Function, using the switch case, in order to be able to determine multiple conditions and output the corresponding value, but when time is equal to 0.3, the simulation will not output the value of this step, it is always skipped. why is this happening? My simulation step size is set to a fixed step size and the step size is 0.1. The input of the function is the clock.
Programm:
function y = fcn(u)
switch u
case 0.1
y=1;
case 0.2
y=2;
case 0.4
y=3;
case 0.3
y=4;
otherwise
y=6;
end

This is a floating-point data equal or non-equal comparision problem. Do this to get an idea.
