%PRWAITBARONCE Generate single prwaitbar message
%
% PRWAITBARONCE(STRING,PAR)
%
% INPUT
% STRING - String with text to be written in the waitbar,
% e.g. '%i x %i eigenvalue decomposition: '.
% This will be parsed by S = SPRINTF(STRING,PAR{:});
% PAR - scalar or cell array with parameter values
%
% This routine has to be used in combination with PRWAITBAR(0), e.g.:
%
% prwaitbaronce('%i x %i eigenvalue decomposition ... ',{n,n})
% [Q,L] = eig(H);
% prwaitbar(0)
%
% It makes clear to the user what is happening in case progress cannot be
% accessed.
