Hello guys,

You can use sprintf() to build the legend string from literal text and an assortment of variables. For example:

% dummy parameters
p=[1 2 3];

x=linspace(0,1,100);
for n=1:numel(p)
	y=x.^p(n);
	subplot(1,numel(p),n)
	plot(x,y)
	legend(sprintf('y=x^%d',p(n)),'location','northwest')
end

Yields us this plot:

Thank you for the answer but i just want to show the constants in my legend but not the graph of my constants. So i just work with the sprintf ?

If all you need is the legend, just use that. The rest is just context for sake of the example.
