generates a square wave with period 2*%pi
x=squarewave(t [,percent])
real vector, time discretization
real vector, the wave value at each time point in set (-1,+1)
real positive scalar, the percent of the period in which the signal is positive. Default value is 50.
squarewave(t)
generates the vector of the values
of the square wave with period 2*%pi at each date given in the
t
vector.
squarewave(t,percent)
generates a square wave such that
percent
is the percent of the period in which the signal is
positive.
