function outval = EDB1myvalueinput(textstr,nvalues,minval,maxval)
% EDB1myvalueinput - Prints a text on the screen and waits for a numerical to be input.
% Prints the text in textstr, and waits for a numerical to be input.
% It is checked if these are within the range [minval,maxval].
% If one or both is not specified, or given as [], an open range
% is used. It is also checked if exactly nvalues are input. The
% values should be input with spaces inbetween. If a negative
% value of nvalues is input, any number will be accepted.
%
% Input parameters:
%   textstr             A text str which will be printed on the screen.
%   nvalues             The number of numerical values that should be read in from
%                       the keyboard.
%   minval (optional)   The lowest value that should be allowed.
%   maxval (optional)   The highest value that should be allowed.
%
% Output parameters:
%   outval              The nvalues numerical values that should be read in.
%
% Uses the function EDB1extrnums
