Adding sentences with calculated numbers to a plot

I want to add 3 sentences with a calculated numbers underneath a plot. I tried using a second line in the x-label, which works, but it doesn't calculate the number. Is this even possible?

[madhan ravi]

can you describe by pasting your code and what's your desired output?

What do you mean?? Perhaps you are looking to put the content of a numerical variable in a string? If so, then you're looking for sprintf

Use the text (link) function.

Example —

x = 1:10;
y = rand(1,10);

AB = rand(1,2);

figure
plot(x, y)
xext = get(gca, 'XLim');
yext = get(gca, 'YLim');
text(1.4*xext(1), yext(1)-0.1*diff(yext), sprintf('The value of A is %.3f\nThe value of B is %.3f', AB))

Experiment to get the result you want.
