I'm using ga at command line to perform optimization. The syntax is as follows: [Go,fval,exitflag,output] = ga(@fuel_eco,nvars,A,b,LB,UB,option) "fuel_eco" is a function which most certainly returns a double value. Yet when I run the code, an error pops up saying: GA only accepts inputs of data type double
Where might the problem lie? Kindly help, I'm grappling with this problem for a long time now.

Your problem has a very simple solution. As detailed in the function reference page, the proper syntax for GA is
ga(fitnessfcn,nvars,A,b,Aeq,beq,LB,UB,nonlcon,options)
You are missing the Aeq, beq entries. As explained in the function reference page, if they don't exist for your problem, replace them with [].
