How to enter variable names into plot title (R2019a)

Hello,

I am trying to enter a variable name into my plot title and it keeps failing. I have been looking up examples that have worked previously but I think that it is different in this version.

clc; clear all; close all;

x = -10:0.001:10;

% 2D Gaussian

m = [0 1 2 3 4 5]; s = [1 2 3];

for i = 1:5 %When the standard Deviation stays the same

p = (1/(s(1)*sqrt(2*pi))).*exp(-(x-m(i)).^2/(2*(s(1))^2));

figure (i);

plot(x,p);

title('2D Gaussian when mean is' m(i) ' and standard deviation is's(i));

end

This is the code that I have used right now. But Even when its not working. I even tried using [] to encapsulate the title and I tried using %f for the variables, but none of that seems to work. Does anyone have any advise for me?

Thank you

Answer 1

 title(sprintf('2D Gaussian when mean is %.2f and standard deviation is %.2f', m(ii), s(ii)))

Index exceeds the number of array elements (3).

Error in Project3 (line 9)

title(sprintf('2D Gaussian when mean is %.2f and standard deviation is %.2f', m(i), s(i)));

I got this error message when I tried this. I also tried m(ii) and s(ii), but MATLAB did not recognize it

[madhan ravi]

title(sprintf('2D Gaussian when mean is %d and standard deviation is %d', m(i), s(1)));

title("2D Gaussian when mean is " + m(i) + " and standard deviation is " +  s(i))

Index exceeds the number of array elements (3).

Error in Project3 (line 9)

title("2D Gaussian when mean is " + m(i) + " and standard deviation is " + s(i));

I got this error message when I tried this code. I also tried ' instead of ", but that also did not work

check what are m, s, i, title in YOUR code
