When I am running the code I am getting the error in if statment that the matrix dimensions do not match.I have written the code to find snm of buttrfly curve of sram ie find side of square in a butterfly curve.Please help me.

[a,T,aT]=xlsread('C:\Users\De80\Desktop\inverterA.csv')
t=a(:,1);y=a(:,2);
[b,bT,bT]=xlsread('C:\Users\De80\Desktop\inverterB.csv')
s=b(:,1);r=b(:,2);
[th, q] = cart2pol(t, y);
[nx, ny] = pol2cart(th+pi/4, q);
[th_1, r_1] = cart2pol(s, r);
[nx_1, ny_1] = pol2cart(th_1+pi/4, r_1);
plot(nx,ny,'red')
hold on
axis square;plot(nx_1,ny_1,'red')
[xi,yi]=polyxpoly(nx,ny,nx_1,ny_1)
if((nx_1)<(xi))
    z1=abs(ny-ny_1);
    c1=max(z1)
    d1=c1.*(1.414);
end
if((nx_1)>(xi))
    z2=abs(ny-ny_1);
    c2=max(z1)
    d2=c1.*(1.414);
end
d=min(d1,d2)
disp(d)

Inside the if statement, in the values compared one is a matrix and the other is a single value. For more information please refer to the below answer as well:
