# twinkle

highlights one or more graphical objects by flashing them

### Syntax

twinkle twinkle(n) twinkle(h) twinkle(h,n)

### Arguments

- h
handle or vector of handles of one or several graphical entities to blink. By default, the current graphic entity pointed by

`gce()`

is considered.- n
positive integer number: the number of blinks. Default n = 5.

### Description

`twinkle`

blinks `n`

times graphical entities
handled with `h`

. If some of the objects are initially invisible,
they are blinked with other ones and are finally left invisible before returning.

If `twinkle()`

is run while no graphical figure exists,
it does nothing and returns. If the handle `h`

has some invalid
components (the entity has been deleted in the meantime),
`twinkle(h..)`

yields an error.

### Examples

clf plot() twinkle // twinkles the last group of curves plotted in the plot() example twinkle(3) // twinkles it only three times clf x = linspace(-2*%pi,2*%pi,100)'; plot2d(x,[sin(x),cos(x)]); e = gce(); p1 = e.children(1); p2 = e.children(2); twinkle(p1) // cos plot twinkle twinkle(p2,10) // sin plot twinkle 10 times twinkle(gca()) // axes twinkle
