2 views (last 30 days)
i worked out the following code for my college assignment, and i got the error message as "consider for preallocation of speed "for the variable A. I've got this code from https://www.mathworks.com/matlabcentral/fileexchange/47281-fuzzy-traffic-light-controller for reference. i don't know how to clear this message pls help me.
A(i)=ceil(((x(b(i))+(enter/exit)*time); % warning message

It is not an error message; it is just a warning. Pre-allocation helps make the code faster. Read my answer here to get a general idea: https://www.mathworks.com/matlabcentral/answers/614903-for-loop-preallocation-warning
