When I run this code I keep getting the invalid expression error message. How can I fix this? The error occurs at line 28 and 40.
clc; clear;
tic
n = 360;
r1 = 3.3;
r2 = 0.82;
r6 = 1.85;
rcg3 = 2.12;
th1 = pi/2;
th2 = linspace(0,2*pi,n);
th4 = 0;
th6 = 63*(pi/180);
formulation
th3guess = -1.5;
r3guess = 4.2;
r4guess = 1.2;
r5guess = 2;
m = zeros(n,4);
for i = 1:n
[th3,r3,r4,r5] =
NR(th1,th2(i),th4,th3guess,th6,r1,r2,r3guess,r4guess,r5guess,r6);
th3guess = th3;
r3guess = r3;
r4guess = r4;
r5guess = r5;
m(i,:) = [th3,r3,r4,r5];
end
function [th3,r3,r4,r5] =
NR(th1,th2,th4,th3guess,th6,r1,r2,r3guess,r4guess,r5guess,r6)

Add ellipses (...) to the ends of lines when you want to continue the statement to the next line:
clc; clear;
tic
n = 360;
r1 = 3.3;
r2 = 0.82;
r6 = 1.85;
rcg3 = 2.12;
th1 = pi/2;
th2 = linspace(0,2*pi,n);
th4 = 0;
th6 = 63*(pi/180);
% formulation
th3guess = -1.5;
r3guess = 4.2;
r4guess = 1.2;
r5guess = 2;
m = zeros(n,4);
for i = 1:n
[th3,r3,r4,r5] = ...
NR(th1,th2(i),th4,th3guess,th6,r1,r2,r3guess,r4guess,r5guess,r6);
th3guess = th3;
r3guess = r3;
r4guess = r4;
r5guess = r5;
m(i,:) = [th3,r3,r4,r5];
end
function [th3,r3,r4,r5] = ...
NR(th1,th2,th4,th3guess,th6,r1,r2,r3guess,r4guess,r5guess,r6)
% stuff goes here
th3 = 0;
r3 = 0;
r4 = 0;
r5 = 0;
end
