IRF: too many inputs arguments?!!!!

Hey every body,

Please I am runing the code for fig03 but it show the following error:

Error using irf
Too many input arguments.
Error in fig03 (line 160)
  Yo0 = irf(1, nir+1, Do, zeros(7, ns), Go, Ho);

I said that because it is irf2 needed and not irf as mentioned in the comments of the code but another kind of error raises:

Error using zeros
Size inputs must be scalar.
Error in irf2 (line 31)
K = zeros(NK, NIR);
Error in fig03 (line 160)
Yo0 = irf2(1, nir+1, Do, zeros(7, ns), Go, Ho);

any help from the matlab community is more than welcome

This line:

Yo0 = irf2(1, nir+1, Do, zeros(7, ns), Go, Ho) ;

YOu cannot input variables like that.

Use:

N = 1 ;
ZZ = zeros(7,ns) ;
Yo0 = irf2(N, nir+1, Do, zZ, Go, Ho)

But this will arise different errors now in irf2...:)

This is incorrect. It is fine to use function results instead of variables in nearly all cases. The situation with calling zeros there is the same as the situation with passing in nir+1, both are the result of expressions

[KSSV]

I tried passing zeros(7,ns), but code trowed error...it accepted input's as a variable.

Hey KSSV, I followed your suggestions by adding the three lines and using the irf2 not irf but the problem is here with different error messages but the figure is not drawing. thanks for your help

[KSSV]

I already mentioned it will give different error messages. :)

What are some sample inputs to test with?

Good morning, Dear @Walter Robenson I didn't understand your question, but I attached the whole zipped file with data and codes above. thanks

fig03 is a function that needs to be passed parameters. What parameters are you passing to it?
