Err0r within code

Please Im facing this errors in my code. Please any help will be appreciated.

Error in tvf_emd>extendsignal (line 343)

endInds = FastCrossing(y,y(nPoints));% find points index has the same level

Error in tvf_emd (line 49)

y=extendsignal(y,num_padding); % padding to deal with boundary effect (match slope)

Please the code and the data is attached.

What is the difference between this question and your later https://www.mathworks.com/matlabcentral/answers/481412-error-using-horzcat-dimensions-of-matrices-being-concatenated-are-not-consistent ?

[Yussif M. Awelisah]

I appreciate your concern. the difference is that this time i suppressed the previous definition of y and used this

  y=extendignal(y,num_padding); % padding to deal with boundary effect (match slope) 
  

instead of

%  y = [fliplr(y(2:2+num_padding-1)) y fliplr(y(end-num_padding:end-1))]; % padding to deal with boundary effect (symmetric)

[Walter Roberson]

No definition for function zerocross ?

[Yussif M. Awelisah]

The function is for 'S crosses level'

No function for zerocross

[Walter Roberson]

Your code contains the line

ind = zerocross(s);

but there is no other reference to zerocross in what you posted. In context it can only be a function.

Your code for your function extendsignal() is clearly written for the case where the input is a row vector, but you are passing in a 500 x 231 array instead. Even if you do not run into problems with array size mismatches, it will obviously not produce the correct answer for the case where each row or each column of the 2D matrix is to be considered independently.

how can this be solved.
