Using an array as input argument of a function handle

Hi,

I have a jacobian matrix created using symbolic variables and I was evaluating it using "subs" command. However, I was recommended to use matlabFunction and handleing it as a function handle. The dymensions of the jacobian matrix depend on my system structure and therefore its size is variable, so I am trying to create a generic code.

There is no problem creating the function handle.

(...some code)

        % Function handle of Jacobian
        J = matlabFunction(J);

and J is:

J =

  function_handle with value:

    @(V1,V2,V3,V4,theta1,theta2,theta3,theta4)reshape...

My problem comes here. If I design input arguments using a variable which is an array:

    a = [1,1,1,1,0,0,0,0];
    J_num = J(a);

I get the following error:

    Not enough input arguments.
    
    Error in
 
   symengine>@(V1,V2,V3,V4,theta1,theta2,theta3,theta4)reshape([V1.*V2.*cos...

However, If I put it like this it works perfectly:

   J_num = J(1,1,1,1,0,0,0,0);

Can anyone can help me?

Thank you in advance!!!

c = num2cell(a);
J_num = J(c{:});
