Subscripted assignment dimension mismatch.

Please I am grateful for your concern. My code use to have a horzcat dimensions but I received great support from here which helped a lot. The below problem still exist. This occurs because one sample of my data is 1 x 500 and Im running the code on 231 samples of data with matrix 231 x 500.

The imf of each samples is 50 x 500 but the data of the 231 samples turns to multiply the number of samples(231) by 500 which results in 50 x 115500 instead of looping through the imf of the 231 individually.

at this point I need a way to loop through for the imf to be 50 x 500 and not 50 x 1155500 or a way to solve the mismatch of dimension.

error:

Subscripted assignment dimension mismatch.

Error in tvf_emd (line 127)

imf(nimf,:)=y(ind_remov_pad);

the code and data is attached.

This a known person I have contact with.

The code of splinefit has been removed.

Thanks for the notice.

"This occurs because one sample of my data is 1 x 500 and Im running the code on 231 samples of data with matrix 231 x 500. "

It is not completely clear what the problem is: surely you can easily loop over the rows and easily collect the outputs into a cell array. After the loop you can concatenate them, padding as required.

I appreciate your help and concern @Stephen Cobeldick

I tried the loop as below

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

but the below error occurs.

Index exceeds matrix dimensions.

Error in tvf_emd (line 50)

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

I wil be grateful if you can provide any other help.

At this moment, I think the best way is to use the preallocation since the value of y increases within the loop but I dont know the best preallocating method in this case.

I tried using 'zeros' this did not work.

I would be grateful for your help
