Combining matrices of different sizes

Hello I'm trying to combine multiple matrices of different sizes which are extracted from each .csv files.

Sat_total = NaN(1440 , 3*30);
sat = readtable('Place-MyHome-Sensor-Myphone-To-Satellite-PRN_32_41328 AER.csv');
[Sat_temp] = sat_tot(sat);
Sat_total(1:length(Sat_temp(:,1)), 1:3) = Sat_temp;

sat = readtable('Place-MyHome-Sensor-Myphone-To-Satellite-PRN_31_29486 AER.csv');
[Sat_temp] = sat_tot(sat);
Sat_total(1:length(Sat_temp(:,1)), 4:6) = Sat_temp;

sat = readtable('Place-MyHome-Sensor-Myphone-To-Satellite-PRN_30_39533 AER.csv');
[Sat_temp] = sat_tot(sat);
Sat_total(1:length(Sat_temp(:,1)), 7:9) = Sat_temp;

sat = readtable('Place-MyHome-Sensor-Myphone-To-Satellite-PRN_29_32384 AER.csv');
[Sat_temp] = sat_tot(sat);
Sat_total(1:length(Sat_temp(:,1)), 10:12) = Sat_temp;

...

( I used [Sat_temp] = sat_tot(sat) to modify tables been extraced to matrices)

As you can see, i'm trying to combine n*3(n differs for each of them) matrices in row.

Please let me know if there are any better solutions, not by typing them manually.

Thank you in advance.

I would do something like this

% list all file names. You may use dir() function to get them automatically
filenames = {'Place-MyHome-Sensor-Myphone-To-Satellite-PRN_32_41328 AER.csv', 'Place-MyHome-Sensor-Myphone-To-Satellite-PRN_31_29486 AER.csv', ...
Sat_total = cell(1, numel(filenames))
for i = 1:numel(filenames)
    sat = readtable(filenames{i});
    Sat_total{i} = sat_tot(sat);
end
Sat_total = [Sat_total{:}];

Thank you for your help.

But, for the end of the code. With my understand, you're trying to make matrix by arranging them in a row.

But each matrices in the cell have different length which make it unable to arranging them.

Could you help me with it?

Ok. I get it. Do you want to append them with NaNs if they are less then 1440? Also, the attached image is empty.

I have solved it :) Thank you very much
