Answer 1

F = 'the name fo your file';
M = readmatrix(F);
M = reshape(M,6,[]).'

this code will fail if your data length is not an exact multiple of 6

hello

to load your text file use readmatrix

Read matrix from file - MATLAB readmatrix - MathWorks France

then you can use this demo code below to shape the data in 6 columns

as the data length may not be an exact multiple of 6 here I padded the data (28 values) with zeroes at the end to have at the end 30 samples (5 rows). You may want another value or NaN if you prefer

a = (1:28)'  % dummy data vector (column)

a = 28×1

1 2 3 4 5 6 7 8 9 10

cols = 6; % how many columns ? 

%% main code
samples = numel(a);
rows = ceil(samples/cols); % compute how many rows are needed
% padd data to fill all rows 
tmp = zeros(cols*rows,1);
tmp(1:samples) = a;
% reshape the data
b = reshape(tmp,cols,rows);
% flip dimensions
c = b'

c = 5×6

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 0 0
