Why does the second example fail?

here's my code and the response

testvec = [Xc,Yc,sig,A]
ErrTest1 = RMS_Err_func(Image,Xc,Yc,sig,A)
ErrTest2 = RMS_Err_func(Image,testvec)

gives:

ErrTest1 =

      0.0942

Not enough input arguments.

Error in NM_2D_Gauss_fit>RMS_Err_func (line 60)
            r(l,m) = sqrt((l-Xc).^2+(m-Yc).^2);

Error in NM_2D_Gauss_fit (line 46)
ErrTest2 = RMS_Err_func(Image,testvec)

NM_2D_Gauss_fit and RMS_Err_func appear to be your own code.

In your first call you are passing in four inputs to RMS_Err_func. In the second call you are only passing in two inputs. We can only guess that RMS_Err_func needs more than 2 inputs.

Is there no way for the function so see the contents of testvec?

[Walter Roberson]

... Yes?

You are passing it in to the function, so the second argument can examine the contents of testvec.

I suspect that your testvec is a vector that has within it values for Xc, Yc, sig, A . If so then,

temp = num2cell(testvec);
ErrTest2 = RMS_Err_funct(Image, temp{:});

Worked perfectly - Thanks !!
