Not enough input arguments. Need help please.

Again with the same problem, I can't seem to find the solution to this problem. Can anyone find the solution to this problem.

function [kurtosis_1] = feature1(data,fs)
    data=data/max(abs(data)); 
    cutoff=100;
    b = fir1(100,2*cutoff/fs,'high',chebwin(101)); 
    data=conv(data,b);
    kurtosis_1= kurtosis(data);

Error using feature1 (line 3)
Not enough input arguments.

How are you calling feature1()? You aren't just clicking on the green "Run" triangle to run it without supplying any input arguments are you?!?! Please copy ALL THE RED TEXT, not just a small part of it like you did.

[Muhammad Sufiyan]

What red text? Sorry, i'm not too good at this.

[Stephen23]

"The red text" means the complete error message that is displayed in the command window, because it include other important information for us, such as the calling sequence of the functions. So please copy and paste all of the red error message and paste it in a new comment here.

Error using feature1 (line 3) Not enough input arguments.

It only appears this after I click the green 'run' button. Nothing else. How?

Please, Muhammad, be so kind and tell us, which is the "line 3". It cannot be "cutoff=100;", so I guess that there is an empty line anywhere? What is "data"? Is it a function handle?

The green button on the toolbar runs code, but does not (by default) provide any arguments. You can use its default behavior for running:

• functions that do not require any input arguments
• scripts

Or you can alter the button's behavior by clicking Run just under the button and defining the code to get run:

Dear Muhammad,

It seems that the function "feature1" needs more then two arguments. If you type in the MATLAB prompt:

>> edit feature1.m

You find the source code of feature1.m. Here you can see how many (and which) additional arguments you need.

Kind regards, Christiaan

[Muhammad Sufiyan]

That is the source code of feature1.m, and i'm not too sure what additional arguments need to be added.

[Christiaan]

Dear Muhammad,

Since feature1.m is a hand made code, please copy the source code of feature1.m in this forum. How this can be done, is described in my answer from before.

Kind regards, Christiaan
