how to fix a genetic algrithm function probelem

Hi, Had an error when I ran this on the matlab prompt:

??? Error using ==> preProcessLinearConstr
The number of rows in A must be the same as the length of b.

Can anyone help out ? N.B : The mfile: multiplesegments exists and has been added to path.

FitnessFunction=@multiplesegments ;
numberofVariables=20;
PopInitRange=[95  3  95  3  95  3 95 3  95  3  95  3  95  3  95  3  95  3  95  3; 115 3  115 3  115  3  115  3  115  3  115 3  115  3  115 3  115 3  115  3];
[x,fval]=ga(FitnessFunction,numberofVariables,PopInitRange)

       [x,fval]=ga(FitnessFunction,numberofVariables,PopInitRange)

This does not resemble the input syntax of ga() described in its documentation. You should be using the options argument in

x = ga(fitnessfcn,nvars,A,b,Aeq,beq,LB,UB,nonlcon,options)

to control the PopInitRange.
