fontsize.m

JLAB is a set of Matlab functions I have written or co-written over the past fifteen years for the p

function[]=fontsize(i1,i2,i3,i4)
%FONTSIZE Rapidly set title, axes, label, and text fontsizes.
%
%   FONTSIZE(TITLES, LABEL, AXES, TEXT) sets the fontsizes of all 
%   titles, x/y/z labels, axes, and text objects in the current
%   figure to the specified values.  To avoid changing a fontsize,
%   use the empty set: FONTSIZE(14,[],12)
%	
%   FONTSIZE('NAME'), where NAME refers to a  predetermined set
%   of font sizes, also works.  Type FONTSIZE with no arguments
%   to see a list of available fontsize sets. 
%
%   When the input arguments are numbers (not named variables) or
%   a string referring to a fontsize set, parenthesis may be omitted.
%   For instance: 
%  
%	    FONTSIZE 14 12 12 10
%	    FONTSIZE DEFAULT   
%
%   Additional fontsize sets may be added to the M-file FONTSIZESETS.
