Not enough input arguments.

I'm new to matlab and am getting the following error

Not enough input arguments.

Error in epithelialTransportFunc (line 20)

G = IC(1);

I'm setting the functions as the following:

% create temporary variables for cell concentrations to make it easier

% to read code

G = IC(1);

Na = IC(2);

K = IC(3);

Cl = IC(4);

The input fuction is the following

function [Cout] = epithelialTransportFunc(t, IC, cs, sglT, NaK, NaCl, ...

glut, perm, cc, nT, mPot, F, R, T)

My guess is that you have a function named IC with two or more required inputs. But you're treating IC as variable so when you index IC(1) you get the error.

To confirm this, run

which IC -all

If this isn't the problem, provide the entire copy-pasted error message.

Answer 2

[Martin Pieters]

When I run IC -all I get the following error

>> IC -all

Unrecognized function or variable 'IC'.

Also how do I model the file from the GUI and run the GUI?

Im running Matlab R2019b version

MOP

Sharing error messages is extremely helpful but we need the entire copy-pasted error message; all of it.

Also, this isn't what I suggested you do. Look again.

Answer 3

[Star Strider]

You did not pass ‘IC’ (and likely others) as an argument.

Check to be certain you are calling the function correctly in your script. You must call it with all the input arguments, and those arguments must be present in your workspace. You cannot run it by clicking on the green ‘Run’ arrow in the Editor.

Answer 4

[Martin Pieters]

Attched is the error message

>> epithelialTransportFunc

Not enough input arguments.

Error in epithelialTransportFunc (line 20)

G = IC(1);

I can also share the code if that would help.

[Star Strider]

No need to share the code, at least not right now since that’s not where the problem is.

Be absolutely certain that all the argumetns are present in your workspace, and then call the function in your script as:

Cout = epithelialTransportFunc(t, IC, cs, sglT, NaK, NaCl, glut, perm, cc, nT, mPot, F, R, T)

Running it (without a semicolon at the end of the line) should print ‘Cout’ to your Command Window.

[Adam Danz]

The error happens at this line

 G = IC(1);

which indicates IC may be a function with 2 or more required inputs (as my answer explains).

Once again, please run this line of code which you havne't done yet.

which IC -all
