n=27
while n>1
n=n-1;
shiptext= [22 6;38 21;24 36;2 30;6 2;15 31;22 15;24 15;10 33;29 11;32 15;29 21;31 4;25 27;29 27;10 11;35 17;15 14;22 20;21 29;23 22;3 22;33 9;8 38;10 4;11 29];
shipnumber= size(shiptext,1);
disp(shipnumber);
plot(shiptext(:,1),shiptext(:,2),'.')
idr1=randi(26,1,1);
row1=shiptext(idr1,:);
idr2=randi(26,1,1);
row2=shiptext(idr2,:);
a=row2-row1;
xdistance=a(1);
ydistance=a(2);
distance=sqrt(((xdistance)^2)+((ydistance)^2))
disp(distance)
if
distance<0.5
disp('warning')
end
end

Hi Josh,
The condition for the if statement must be placed side rather than in next line.
Update the code of if statement with this:
if distance<0.5 % the condition should be inline with the 'if'
disp('warning');
end
This should solve.
Regards,
Sriram
end
