c is a vector, so what is x(c) supposed to mean?
Can you just post the equations you are trying to code and we can help you code them?

One approach is to write x,y, and A as matrix-valued anonymous functions of c, e.g.,
x=@(c)(4-c)./(6+c);
y=@(c)10./(6+c);
A = @(c) [-1-2.*x(c)+y(c) x(c);-6.*y(c) 4-2.*c.*y(c)-6.*x(c)];
fplot(@(c) trace(A(c)), [0,2.23])
xlabel 'c'
ylabel 'Trace(A(c))'
