How to call Mathematica in Matlab to evaluate the symbolic anonymous function?

% I need to perform symbolic calculations
x1 = sym('x1');
x2 = sym('x2');

% The actual expression is very complicated
% The following expression is just an example
expression = x1.^2 + x2.^2;
% The following anonymous function is defined
% to evaluate the value of the expression
Fobj_sym = @(sol1,sol2) double(subs(expression,{x1,x2},{sol1,sol2}));

sol1 = sym('1');
sol2 = sym('2');
% I need to evaluate the anonymous function multiple times
% The execution of the following anonymous function took too much time
% MuPAD seems too slow to use  
Fobj_sym(sol1,sol2)

% Q:How to call Mathematica in Matlab to evaluate the anonymous function?
% I have no experience with Mathematica

I installed the following toolbox, but I don’t know how to solve this problem.

Try this code

syms x1 x2

expression(x1, x2) = x1.^2 + x2.^2;
expression(1, 2) % evaluate with x1=2, x2=2

Thanks for the reply, unfortunately it runs twice as slow as the method in the question.
