Scilab Help >> Elementary Functions > Matrix generation > squarewave


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.


t = (0:0.1:5*%pi)';
plot2d(t, [2*sin(t), 1.5*squarewave(t), squarewave(t,10)])
