Error in Y label

So I was trying to make graph for my homework assignment on Matlab online version using this code:

% disp("HM Problem 3")
disp("f1(x)")
x=[-5,0.5,5];
y=(2*x).^3-(3*x)+2;
plot(x,y);
grid on;
legend({'f(x)=2x^3-3x+2'},'fontsize',10)
xlabel('Input Values','fontsize',10)
kylabel('Value of the function','fontize',10)
title('function 1','fontzie',10)

But when I enter my code is says "Error using matlab.graphics.primitive.Text/set. Unrecognized property fontzize for class tex." and then another error saying "Error in ylabel(line 73) set (h, 'string', string, prvpairs{:});

In the code you have:

kylabel('Value of the function', 'fontize', 10)
title('function 1', 'fontzie', 10)

The error message says:

Unrecognized property fontzize for class tex

Neither "fontize" nor "fontzize" nor "fontzie" are correct, but "fontsize".

But maybe it is a typo in the forum only. The "kylabel" is surprising also.

Please copy&paste the code and the complete error message.
