# squarewave

generates a square wave with period 2*%pi

### Syntax

`x=squarewave(t [,percent])`

### Arguments

t

real vector, time discretization

x

real vector, the wave value at each time point in set (-1,+1)

percent

real positive scalar, the percent of the period in which the signal is positive. Default value is 50.

### Description

`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.

### Examples

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

### See also

• sin — sine function
• cos — cosine function
