I want to use Genetic Algorithm for optimization.
I have 5 variables (a,b,c,d,e), at the optimized solution, these variables values would be between 0 and 1.5.
The objective function which I want to minimize is x.
I don't want to construct a relation between objective function and these variables due to certain internal complex operations. Instead, I have a software where I plug the values of a,b,c,d,e and it gives be the value of X.
So instead of an equation to optimize I want to use my software to give the result value of X.
So I need to know the code to get next iteration/combination of (a,b,c,d,e) so I can plug them in my software and give the resultant X value to MATLAB so it can update and give me another set of iterations.

Do you have the Global Optimization Toolbox? That's the first step if you want to use GA.
Try writing your objective as something like this:
function objectiveVal = myFunction(x)
a = x(1);
b = x(2);
c = x(3);
d = x(4);
e = x(5);
% Call your other software
objectiveVal = otherSoftwareCall(a,b,c,d,e);
