Details:

it would be nice to modify the square function, that one could work with
integer cyclic frequencies without tunings about rounding error. At least it
would be nice to have an option to square that menas, that the default period
is not 2pi, but 1.

>> square(linspace(0,1,9)*4*2*pi)
ans =

   1  -1   1  -1   1  -1   1  -1   1

>> square(linspace(1,2,9)*4*2*pi)
ans =

   1  -1   1   1   1  -1   1   1   1

>>
