- Add NaN during the beginning or end of the data (like pad array concept)
- You can then interpolate data in between to make the same length.
- Delete (Peridic wise) data from a larger one, so that both files fit equal.
How to assign NaN to an empty cells in array for data arrangement?

Hi,
Currently, I'm trying to arrange my data in .txt. file of certain column in an .xls file.
But I got this error, as the dimension of each selected column of the .txt file are not similar.
Error using horzcat
Dimensions of arrays being concatenated are not consistent.
I plan to assign NaN to the empty cell to obtain similar dimension of each data.
What are the best solution for this problem?
Attached herewith the .txt. file and command I had tried.
S1 = importdata ('s1.txt');
%Read the data
GRFX1 = S1.data(:,2);
GRFY1 = S1.data(:,3);
GRFZ1 = S1.data(:,4);
S2 = importdata ('S2 0.txt');
%Read the data
GRFX2 = S2.data(:,2);
GRFY2 = S2.data(:,3);
GRFZ2 = S2.data(:,4);
S_1 = [GRFX1,GRFY1,GRFZ1];
S_2 = [GRFX2,GRFY2,GRFZ2];
GRFX=[GRFX1, GRFX2];
GRFY=[GRFY1, GRFY2];
GRFZ=[GRFZ1, GRFZ2];
%Arrange the data in one sheet before convert to .xls file
N = [S_1, S_2];
GRF = [GRFX, GRFY, GRFZ];
Thank you in advance!

Please try with readtable, it replaces all missing data with NaN.
Note: Text files have unwanted header descriptions, you can delete them so that there is no problem when analyzing both files. However, if both files have different length data (originally), then you have the following options
