Invalid expression. Check for missing or extra characters.

Hi
When I run my code I got an error message "Invalid expression. Check for missing or extra characters" for my if loop.
I am not sure why. Someone there can help me?
GHGS = (zx(:,[151+[-1 0 1]])-zx(:,[131+[-1 0 1]]))/20;
GHGN = (zx(:,[171+[-1 0 1]])-zx(:,[151+[-1 0 1]]))/20;
for i=1:nx
if
GHGS > 0
fprintf('The point is blocked')
elseif
GHGN < -10
fprintf('The point is blocked')
else
blocks(i)=blocks(i)+1;
end
end

At a guess I would say it comes from splitting your if condition across 2 linies, though I haven't tested it.
Try
if GHGS > 0
all on one line instead.
You can split code across multiple lines, but it need the first line to end with ... to show that the same statement continues on the next line, otherwise Matlab will expect a complete statement on the first line.

GHGN = (zx(:,[171+[-1 0 1]])-zx(:,[151+[-1 0 1]]))/20;
for i=1:nx
if GHGS > 0 %change your lines to this as one line
fprintf('The point is blocked')
elseif GHGN < -10 %change your lines to this as one line
fprintf('The point is blocked')
else
blocks(i)=blocks(i)+1;

The equation is in .mlx file and I saved as .m file to paste the code(syntex) for .mfile execution. facong below error :
% Mutual Inductance
g = 1.3 ; % constant value for square shape.
n1 = 5 ; % number of turns in primary coil
n2 = 4 ; % number of turns in secondary coil
r_i = % radius of ith turn in primary coil
r_j = % radius of jth turn in secondary coil
d_12 = 30 ; % distance between coils,mm
M=g\sum_{i=1}^{n1}\sum_{j=1}^{n2}(M_ij,r_i,r_j,d_12)
> squarecoil
Error: File: squarecoil.m Line: 53 Column: 44
