D3=5;
Q1=4;
Q2=5;
Q3=6;
V1=4*Q1/(3.14*D1^2);
V2=4*Q2/(3.14*D2^2);
V3=4*Q3/(3.14*D3^2);
P1=5*D1^2;

You need to define Vi and Pj. For example:
Vi = 5
Pj = 22
or whatever. If you do that, it runs.

Your objective function is going to receive a vector of values in a single variable. Extract portions of that vector into variables inside the function. Use vectors and index them as needed.

function cost = obj(x)
P = x(1:10) ;
V = x(11:18);
cost = sum((P-7).^2) + sum((V-100).^2) ;

is now the way correct. I have put indices on each letter. How to write and correlate the summation and if- else statement in the program.

@adarsh: Do not let the expression "Q1,Q2,Q3, ..." confuse you. Later in the document Q is an array and an index is used: Q(1), Q(2), ... Using vectors is the right way to go.
