% Get a number typed at the keyboard. Entry is terminated by
% <return> or <enter>. Typed keys are not echoed. Useful for
% i/o in a Screen window. Equivalent to "number=str2num(GetString)".
%
% Returns the empty matrix if no number is entered. Returns a
% column vector with multiple numbers if more than one number
% is entered.

% 12/7/95 dhb Wrote it in response to query from Tina Beard.
% 3/15/97 dgp Replaced sscanf by str2num, which copes better with nonnumeric
% input, returning an empty matrix instead of a null string.
% 3/15/97 dgp Call GetString instead of doing the work here.
% 3/17/97 dhb Got rid of obsolete 's' interface.
% 10/22/10 mk Switch to use of KbGetChar for keyboard input.
