What we are doing at Rice is a modification of the setup used at Notre
Dame by Nancy Stanton, and developed there by Johanes Suhardjo and
Henry Harbury. Due to the new features that allow the windows in
pplane to be resizable and the
default figure positions to be changed using global variables, the
setup can be affected without tampering with the code in
In MATLAB v. 4 under UNIX, there are three separate classes of fonts, each of which is controlled in a different way.
xterm -g 70x30+20+20 -fn <fontdes> -fb <fontdes> -e matlabwhere <
fontdes> is a font designation such as
"-*-courier-*-r-*-*-*-200-*-*-*-*-*-*"Fonts can be previewed and their designations found using the UNIX/X Windows utility
pplane. They are XResources, and they can be changed using the command
xrdb. Once changed, they remain in affect until they are changed again or until you log out of your computer.
A convenient way to do this is to put the new resource into a file
with a name such as
.Matlab, with the contents
figure*fontList: -*-helvetica-*-r-*-*-*-240-*-*-*-*-*-*Then executing the command
xrdb -merge .Matlabwill effect the change. You will notice that the code coming after the colon in
.Matlabis a font designation as described above.
setas described in the MATLAB documentation.
For example to change to a 20 point font as the default in all figures and axes, the commands
set(0,'defaultaxesfontsize',20); set(0,'defaulttextfontsize',20);will suffice.
A convenient way to change defaults consistently is to do it in a
startup.m file. This file is executed by MATLAB as part
of its start up procedure.
set. Again the defaults can be changed for all subsequent figures, or the user can change the charateristics of individual figues.
Again it is convenient to make these changes in the
pplanefrom the same source as the students. In addition we want the commands used in class to be the same as those used by the students, so that they are not confused. To resolve this we use code that branches on the
hostnameof the computer being used.
To call up MATLAB, we use a shell script which is really a complicated
alias with the name
matlab. The contents are:
if [ "`hostname`" = "trigger" ] || [ "`hostname`" = "grenadier" ] then xrdb -merge /home/math211/bin/.Matlab xterm -g 65x24+20+20 -fn "-*-courier-*-r-*-*-*-200-*-*-*-*-*-*" -fb "-*-courier-*-r-*-*-*-200-*-*-*-*-*-*" -e /usr/site/matlab/bin/matlab & else eval '/usr/site/matlab/bin/matlab' fiThe file
.Matlab, has the contents:
figure*fontList: -*-helvetica-*-r-*-*-*-240-*-*-*-*-*-*Finally the figure and axis fonts and the default figure positions are set in the
startup.mfile, which is called by MATLAB when it is started. The listing for this file is
% STARTUP.M % % MATLAB startup file to define default font sizes and figure % positions. We also make the line size twice the usual. % First we have to find the hostname of the computer being used. This % is not so easy, since MATLAB does not recognize the output of UNIX % commands. Instead we have to fool it. !hostname > jhlkjhkjlhkhj fid = fopen('jhlkjhkjlhkhj'); hn = fgetl(fid); fclose(fid); delete('jhlkjhkjlhkhj') % If the hostname is not one of those used in the classroom we do % nothing.
