I had to fix another error first.
Error in main (line 14)
Aineq=[0,6,-1,0,0,0,o,o];
It looks like you added the letter "o" instead of the number 0 for the last 2 values.
The red text that follows the warning is there to help you find and fix the error.
The number of columns in A must be the same as the number of variables.
The error pointing back to main is the one you should look at:
Error in main (line 23)
[x_gal,fval_gal,~,gaoutput1]=gamultiobj(fun,7,Aineq,bineq,Aeq,Beq,lb,ub,@nonlcon,opts_ga);
You say you have 7 variables, but Aineq contains 8 values. Change your nvars input to 8 (or Aineq and Aeq to 7 values) and this warning and error will go away..

I'm not familiar with your equation or your application, so can't comment extensively. Perhaps all other solutions are considered inferior to this single solution. This may be because of the high dimension of your equation (8), or the constraints you have placed on them, or of the problem space itself.
