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.
