Not Enough Input Arguments

I've been trying to run the following function, but cannot get it to run without the above error. I have a script file that includes values for all of the input arguments listed. Can anyone spot an error that I'm missing?

function [ New_Phi ] = New_Phi_well( x,y,xw,yw,rw,Q,L,d,Qx0,Phi0 )
rsq=(x-xw)^2+(y-yw)^2;
rwsq=rw^2;
if rsq<rwsq
    New_Phi=0;
else
    New_Phi=Q/(2*pi)*(log(rsq/rwsq)/(log(L-d)-log(L+d)))-Qx0+Phi0;
end
end

It is simple.....you are not providing all the inputs the functions needs.

I just done this and it does work for me.

 function [ New_Phi ] = New_Phi_well( x,y,xw,yw,rw,Q,L,d,Qx0,Phi0 ) 
 x=10,y=2,xw=3,yw=4,rw=5,Q=3,L=5,d=6,Qx0=2,Phi0=1; % I've just used random values, try using 'input' (asking user input here)
 rsq=(x-xw)^2+(y-yw)^2; 
 rwsq=rw^2; 
 if rsq<rwsq 
    New_Phi=0 
 else New_Phi=Q/(2*pi)*(log(rsq/rwsq)/(log(L-d)-log(L+d)))-Qx0+Phi0
 end

I've got the answer like

New_Phi =

-1.0551 - 0.0722i

when I called 'New_Phi_well' in command window. Also try if the values you said are available and check the current folder option (for the availability of your program or input data called) too. Sometimes this throws errors for me.

Good day.

I was able to produce an answer this way too. I'm also trying to create a plot with varying x's and y's, so I believe there are errors elsewhere outside this function. Thanks for your help!

It is not enough that the script defines values with the same name as the parameters: you have to put the values in the calling sequence positionally.

So for example you cannot define values for x, y, xw, yw, rw, Q, L, d, Qx0, and Phi0, and then invoke

result = New_Phi_well;

You need to instead

result = New_Phi_well( x,y,xw,yw,rw,Q,L,d,Qx0,Phi0 );

providing each variable into its proper position.

[Timmy1400]

Yes, I have that part in my script too. For some reason it still is giving me the "not enough in put arguments" error and specifies it is within the function itself.

We need to see your code and we need to see the exact error message.
