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?

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.
