Why do my plots end up empty?

Hello!

My idea is to plot three graphs in the same same figure using nexttile, and while the plots do show, the functions within them ends up being just empty rectangles with their respective names above them. I'm quite new with Matlab, so any help would be appreciated, even just a slight push in the right direction. :)

Thank you!

See code below:

x = linspace(-2.5,2.5,10);
y1 = x/(x.^2+1);
y2 = (1/3)(x/(1+(1/9)*x.^2));

Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.

y3 = -1/2(x/(1+(1/4)*x.^2));
tiledlayout(3,1)

nexttile
plot(x,y1)
title('Plot 1')

nexttile
plot(x,y2)
title("Plot 2")

nexttile
plot(x,y3)
title("Plot 3")

Your post now shows the result of running your code (I took the liberty). It never makes it past the first 4 lines, as you can see.

If I make some guesses as to what operations you really intended,

x = linspace(-2.5,2.5,10);
y1 = x./(x.^2+1);
y2 = (1/3)*(x./(1+(1/9)*x.^2));
y3 = -1/2*(x./(1+(1/4)*x.^2));
tiledlayout(3,1)

nexttile
plot(x,y1)
title('Plot 1')

nexttile
plot(x,y2)
title("Plot 2")

nexttile
plot(x,y3)
title("Plot 3")
