function [ispace,strout] = iecho(str);%IECHO Indent echo%   [IDT,TAG] = IECHO(NAME) is a useful utility which allows function%   echoes to be indented. The script returns an empty string IDT such%   that is inserted in front of displayed text. Than you don't need to%   take care about prompt indenting any more. To change indent%   spacing set the INDENT variable to the desired value. Default value%   for INDENT is 11 (characters). This means that 11 blank spaces will%   inserted in front of the NAME. INDENT may also be set globally.%%   Example:%     [indent,tag] = iecho('FUNCTION');%     disp(' ');%     disp([tag,'Some echo on the 1st line.']);%     disp([idt,'Some echo on the 2nd line.'])%     disp([idt,'Some echo on the 3rd line.'])%     disp([idt,'Some echo on the 4th line.'])%     disp(' ');%   Copyright 2001-2003 Kamil Anis, anisk@feld.cvut.cz%   Dept. of Radioelectronics, %   Faculty of Electrical Engineering%   Czech Technical University in Pragu%   $Revision: 2.1 $  $Date: 2003/1/16 17:33:28 $%   --%   <additional stuff goes here>global INDENTif ~isempty(INDENT) % than check whether global option exists	indent = INDENT;else % if there are no settings use the defaults	indent = 12; % default valueendif indent <= length(str)	tspace = ' ';else	tlength = indent - length(str) - 2;	tspace(1:tlength) = ' ';endispace(1:indent - 1) = ' ';strout = [str,':',tspace];
