Error using plot, "vectors much be same length"

I am getting the error:

Error using plot

Vectors must be the same length.

Error in HW11part1 (line 12)

plot(-1.5:0.1:1.5,Sxx)

Can you help me fix my code?Thank you!

Code:

L=1;
s=.75;
y=0;
icount = 0;
for xbar=-1.5:0.1:1.5
    icount = icount + 1;
    fun= @(tbar) ((xbar-tbar)^3)/(((xbar-tbar)^2+y^2)^2); 
    Sxx1=integral(fun,-L,-s, 'ArrayValued',1);
    Sxx2=integral(fun,s,L, 'ArrayValued',1);
    Sxx(icount)=(Sxx1+Sxx2);
end
plot(-1.5:0.1:1.5,Sxx)
xlabel('x/L')
ylabel('Normalized Sxx')

Try,

x = linspace(-1.5, 1.5, numel(Sxx))
plot(x,Sxx)

Hmm, my graph is not what I expect. I am graphing now though. Thanks!
