MATLAB: “Not Enough Input Arguments” Error

Question

Hello,

I am working with a code where I am stuck with a "Not Enough Input Arguments" error, even though it looks like the input arguments are listed. Specifically:

function [primeArray hR fA c] = proprioDPrimeAnalysis(oneCM, twoCM, threeCM, fourCM)     
diffInd = find(oneCM(:,1) < -0.001);

the second line defining 'diffInd' causes the error. However, 'oneCM' is already defined as a 30×2 double array in the workspace:

0  0
0  0
0  0
0  0
-0.01   0
-0.01   0
0  1
0  1
0  0
-0.01  0
-0.01   1

0  1

-0.01   1
0  0
-0.01  0
-0.01   1
0  0
-0.01   0
-0.01   1
-0.01   1

-0.01   1
0  0
-0.01   0
0  0
-0.01   1
-0.01   0
0  0

Please let me know if I am missing something, or if there is more I can provide.

Thank you.

How are you calling your ‘proprioDPrimeAnalysis’ function?

You must call it with all the input arguments as:

[primeArray hR fA c] = proprioDPrimeAnalysis(oneCM, twoCM, threeCM, fourCM);

It will not magically pick up any variables from your workspace, unlike anonymous functions.
