How to call a function from simulink, using a matlab function block?

Hello I need youre help. My question is simple and here it goes:

How can i call a matlab function i made from inside a simulink block?

The matlab (Pos_Solve_Allo.m) function looks like this:

function fp = Pos_Solve_Allo(M, F_gen)

%Pos_Solve_Allo.m

lb = [0;0;0;0;0;0;0;0];

ub = [Inf;Inf;inf;Inf;Inf;inf;Inf;Inf]; % lower and upper bounds

% Aeq = [0 1 4/10;1 0 7/5];

% beq = [7/20;2/5];

fp = lsqlin(M,F_gen,[],[],[],[],lb,ub)

end

So inside the function i use lsqlin solver, which cannot be used in matlab function block as is, that is why i included it in the function above.

Inside my matlab function block i call Pos_Solve_Allo in the following way:

function fp = fcn(m)

% Konstants

a = (1/2 + 1/sqrt(12));

b = (1/2 - 1/sqrt(12));

c = (1/sqrt(3));

P = 1/sqrt(3)*[1 -1 1 -1 1 -1 1 -1;

1 1 -1 -1 1 1 -1 -1;

1 1 1 1 -1 -1 -1 -1];

X=[-a b -b a a -b b -a;

b a -a -b -b -a a b;

c -c -c c c -c -c c];

M = [X;cross(P,X)]

F_gen = transpose([0 0 9.8*m 0 0 0]);

Pos_Solve_Allo(M,F_gen) %Here I call the function

end

However i get the following error:

Function 'lsqlin' not supported for code generation.

Function 'Pos_Solve_Allo.m' (#592.199.232), line 7, column 6: "lsqlin(M,F_gen,[],[],[],[],lb,ub)" Launch diagnostic report.

I found a solution to the problem, and in the pictures u can see how it is solved. There exists similar discussion on the topic as well in the matlab questions forum, but heres is how i ended up solving the issue:
