Numel error cant figure out why

for i=1:1:randomvariableforx1secondpoint
if actualshrtestdistancepoint2==distancepointfromotherpointsecondpoint(i)
pointtouse2haha=i;
break;
else ('hahaha no');
end
end
pointtouse2=pointtouse2haha;
% distancepointfromotherpointlel2=sqrt(((xlocation1secondpoint(pointtouse2)/10)-p2x)^2+((ylocation1secondpoint(pointtouse2)/10)-p2y)^2);
% distancepointfromotherpoint2=min(distancepointfromotherpointlel2)
%% newxlocationonsecondlinelel=xlocation1(pointtouse2)/10;
newylocationonsecondlinelel=ylocation1(pointtouse2)/10;
So my variable "randomvariableforx1secondpoint" is 48 and i find the maximum value at 37. so i wanted to use this position of i but for some reason my code uses the value of 48 in the foollowing steps and i get a numel error. can you guys help out? thanks

It looks as though the exact equality demanded by "==" never occurred and so the 'break' did not happen, but your value of 'pointtouse2haha' had previously been set to 48 before the for-loop. Remember, "==" requires precise equality, not just equality within some given tolerance.
