find local minima with range for inputs

I am trying to find the minima for a function for which I pass 5 values. However I cannot get the function to apply my parameters. This is what I have so far:

My objective function is:

function q = my_objective_function(m1,m2,m3,m4,m5)
    q = sqrt(pi*30*6.5*(10^-6).*(m3.*m5/((2.*(m2.^(3/2)).*(m4.^(1/2))))+(((m1+m2).*(m4.^2))/(2.*m5.*(m2.^2)))));
end

I have set the parameters for m1...m5 in the command line as follows:

>>m1 = 30:1:100
%so I have a range for m1 to be from 30 to 100 in 1 increments
%I have done similar for the other 4 m's

In the command window I then write:

>> [x, fval] = ga(@(m)my_objective_function(m(1),m(2),m(3),m(4),m(5)),5)

but my answers still give values that are out of range, for example:

x =

-18.6531 65.5402 -12.9160 9.6649 11.4359

fval =

0.0000e+00 + 3.4396e-04i

How do I apply my parameters for my m's correctly?

nvar = 5'
A = []; b = [];
Aeq = []; beq = [];
lb = 30 * ones(1,nvar);
ub = 100 * ones(1,nvar);
nonlcons = [];
Intcons = 1:nvar;
[x, fval] = ga(@(m)my_objective_function(m(1),m(2),m(3),m(4),m(5)), nvar, A, b, Aeq, beq, lb, ub, nonlcons, Intcons)
