Would it be possible to pass the text of fprintf to the plot's text?
x = rand(1,10);
plot(x)
m = mean(x);
sd = std(x);
a = fprintf('the mean is %1.2f\n',m);
b = fprintf('the standard deviation is %1.2f\n',sd);
text(2,0.5,[a b])

You will need to use sprintf for storing the char array, then using it as inputs to text().
You can either use disp or fprintf on that text for displaying it.
x = rand(1,10);
plot(x)
m = mean(x);
sd = std(x);
a = sprintf('the mean is %1.2f\n',m);
disp(a)
the mean is 0.41
b = sprintf('the standard deviation is %1.2f\n',sd);
disp(b)
the standard deviation is 0.31
text(2,0.5,[a b])

thanks a lot! Yes, also using fprintf with both sentences works well as you mentioned:
x = rand(1,10);
plot(x)
m = mean(x);
sd = std(x);
a = sprintf('the mean is %1.2f\n',m);
b = sprintf('the standard deviation is %1.2f\n',sd);
text(2,0.5,[a b])
fprintf([a b])
the mean is 0.59 the standard deviation is 0.26
