PULSe in Matlab Symbolic

Hi,
I have a approximation of a rectangular function:
function current=pulse(t)
if (t-2.5*round(t/2.5-0.5))<=0.2
current=0.001;
else
current=0;
end
end
Then I need t as symbolic:
syms t;
pulse(t);
BUT I get this ERROR:
Conversion to logical from sym is not possible.
Error in ie1 (line 6)
if (t-2.5*round(t/2.5-0.5))<=0.2
Hope somebody can help. Thank you!

You will have to construct a piecewise function. See http://www.mathworks.com/help/toolbox/mupad/stdlib/piecewis.html.
Note that the MuPAD piecewise() function does not have a MATLAB interface, so you will need to use evalin(symengine) or feval(symengine) in order to create the object.
