How to write matlab code for simplex equation.

How to write matlab code for the simplex equation to maximize P=7x1+8x2+10x3, where x1,x2,x3>=0, and the constraints are assembly and fabrication time labor where equations for Assembly is x1+x2+2x3<=800, and for Fabrication is 2x1+3x2+2x3<=1000.

You would use LINPROG.

On Matt J. Clarification, if you have any idea on the script for the problem. Needs symbolic programming in writing the script. I was doing something like this:

function tab = texas1_simplex(f1,f2,f3,debug)

% f1 is (a1*X1+a2*X2+a3*X3-b1) 
% vars are X1, X2, X3 
% coeffs are a1,a2,a3,a4,a5,a6,a7,a8,a9,b1,b2,b3 
% f1= ('a1*X1+a2*X2+a3*X3-b1')

f1 = input('please enter the equation f1:');

X1= sym ('X1'); X2= sym('X2'); X3= sym('X3');

a1=('_'); a2=('_'); a3=('_'); b1=('_');

c=sym2poly(f1);

but it doesn't run.

You can use the new problem-based approach in R2017b if you want a more symbolic representation for your problem:
