printing value of a variable in a plot at some fixed coordinates

Hi,
I want to plot a graph and then print values of variables at some fixed coordinates each time inside a loop:
%Some initial values
T = 10; nts = 10000;
for a = 1:10
for c = 1:10
[SE, SH, EE, EH, Efeval, Hfeval] = HeunvsEuler(a, c, T, nts);
plot(sign(norm(EE,inf)-norm(SH,inf)),'*');
%I want a function here which can print values of a and c just beside * in above plot
end
end
I know there is a function 'text' but it prints only a fixed string. I need something like 'fprintf' which can print values of variables. Please suggest.
Thanks Ashish

You can use text with num2str or sprintf
doc text
doc num2str
doc sprintf
for example
text(x,y,sprintf('VARNAME=%f',VARNAME))
