newer duplicate questionwhile running i am running this code i getting this error "error using input the second argument to input must be 's'." plz help me

num_nod=input('num_nod  = ')
for e=1:2*num_nod

num_nod=input('num_nod  = ')
for e = 1:2*num_nod
  force(e,1) = input(sprintf('applied forces at node %d: ', e));
end

Ganesh - use sprintf to create your string for the input command

 force(e,1) = input(sprintf('applied forces at node %d:',e));

Also, pre-allocate memory to the force array so that it doesn't need to increase size on each iteration of the loop. i.e.

 num_nod=input('num_nod  = ')
 force = zeros(2*num_nod,1);
 for e=1:2*num_nod
    force(e,1) = input(sprintf('applied forces at node %d:',e));
end

So I was able to change the format of my code and I do not get the error again. However, it gives me a new error:

 Error using makeState (line 56)
Your fitness function must return a scalar value.
Error in gaunc (line 40)
state = makeState(GenomeLength,FitnessFcn,Iterate,output.problemtype,options);
Error in ga (line 356)
            [x,fval,exitFlag,output,population,scores] = gaunc(FitnessFcn,nvars,
            ...
Error in complete_code (line 266)
[x,fval] = ga(@obj_func,3);

Can anyone please tell me what this means? And possibly what do you recommend me to do to make it right? Thank you so very much.
