GetKeyWait

Wait a certain time for a single keypress (v2.1, jan 2012).

Description

GETKEYWAIT - get a key within a time limit
    CH = GETKEYWAIT(P) waits for a keypress for a maximum of P seconds. P should be a positive number. CH is a double representing the key pressed key as an ascii number, including backspace (8), space (32), enter (13), etc. If a non-ascii key (Ctrl, Alt, etc.) is pressed, CH will be NaN.
    If no key is pressed within P seconds, -1 is returned, and if something went wrong during excution 0 is returned.

@Sanchito: I suggest you implement the code/functionality of getkeywait into your own GUI directly.

[Sanchito]

when i am running this program it is making another figure wherein i need to press enter for it to continue.

what I am saying it is that: I have a gui wherein a person enters a node number and then wait for the enter press key.... and i say if ch== 13 then run the rest of the program but when i do press enter it opens a figure wherein i need to press enter again for me to continue the analysis. Is there anyway of me avioding this figure in the middle just directly analysing it as soon as enter is pressed?

thanks

Just what I was looking for

Great. Thank you Jos.
Is it possible to prevent the appearance of figure tab in the task bar?
I'm calling your function in a loop every second, and it works well, but there is continuous blinking between command window and windows task bar as your code opens and closes a figure window each time. I tried to off the 'visible' property of the figure, but it was not working...

Great submission

Thank You! This function worked out for my program wounderfully!

in need of some re-engineering as it creates a new timer object every time it is called, which could be deleterious when used in a long loop, for instance.
