Not enough input arguments

Dear All,

Please, help me with following problem. I can't run the DSGE model (the code is from author) in Matlab. Attached the code.

COEF_NCC_RED

Not enough input arguments.

Error in COEF_NCC_RED (line 7)

aa = subs(eq,{'k_t','m_t','c_t','l_t','z_t','u_t','v_t'},{1,0,0,0,0,0,0});

COEF_NCC_RED is just a function definition. You need to define an equation 'eq' before calling COEF_NCC_RED. For example, run the following lines

syms k_t m_t c_t l_t z_t u_t v_t
eq = k_t+m_t+c_t+l_t+z_t+u_t+v_t;
COEF_NCC_RED(eq)

paste these lines in a new script file and run it. COEF_NCC_RED should be on MATLAB's path (e.g., in the same MATLAB folder).

Ameer, thank you very much. This problem occured when I did your recomandation:

COEF_NCC_RED(eq)

Error using ==

Not enough input arguments.

[Ameer Hamza]

How are you running this function? Have you created a new script, pasted my code, and tried to run it? Also, can you give the complete error message? Everything in the red text.

[ninu]

Yes, I created a new script and after I tried to run it .

This was the red text:

Error using ==

Not enough input arguments.

I runned just this section in the new script:

syms k_t m_t c_t l_t z_t u_t v_t

eq = k_t+m_t+c_t+l_t+z_t+u_t+v_t;

COEF_NCC_RED(eq)

This error does not make much sense with this code. Instead of creating a section, first, try to run this code as a separate file.
