The corresponding function file is shown below for your  reference.


function mutationChildren = ....
      mutationgaussian (parents, options,nvars, FitnessFcn,
                        state, thisScore, thisPopulation);            
#[LB(1, 1:nvars) UB(1, 1:nvars)] =.....
#    __ga_popinitrange__ (options.PopInitRange, nvars);
[LB UB] = __ga_popinitrange__(options.PopInitRange, nvars);
## start mutationgaussian logic
options.MutationFcn(1, 2)
Scale = options.MutationFcn(1, 2);
#scale=1;
  #assert (size (Scale), [1 1]); ## DEBUG
Shrink = options.MutationFcn(1, 3);


I have checked that all the variables are passed to the function by list each
variable separately. Still I am getting this error message.
