Display waitbar

h = waitbar(x,'title')A waitbar shows what percentage of a calculation is complete, as the calculation proceeds.

```
h = waitbar(x,'title')
```

creates and displays a waitbar of fractional length `x`

. The handle to the waitbar Figure is returned in `h`

. `x `

should be between 0 and 1. Each subsequent call to waitbar, `waitbar(x)`

, extends the length of the bar to the new position `x`

.
`waitbar`

is typically used inside a `for`

loop that performs a lengthy computation. For example,
h = waitbar(0,'Please wait...'); for i=1:100, % computation here % waitbar(i/100) end`close`
