I've this txt file:
I'd like that all number (32) that are between the square barckets will be the first rows of a 2D array (matrix) 24x32 .
Anything like this:
Any idea?
Thanks in advance

Hello Cosimo,
I understand you are trying to import the data stored in "acquisizione2-new.txt" into the MATLAB Workspace. This is possible with the Name-Value Pair Arguments available for the readtable function. After importing the data, there is one extra step that is necessary to remove NaN columns in the table output from readtable.
Please try the code given below, hope this helps!
data = readtable("acquisizione2-new.txt",'ReadVariableNames',false,...
'Delimiter',[" ","]","["], 'LineEnding', "]\n",'TrimNonNumeric',true);
% find NaN columns
nanIdx = arrayfun(@(x) all(isnan(data{:,x})), 1:width(data));
% remove NaN columns
data(:,nanIdx) = [];
% convert to numeric array (optional)
dataMatrix = data{:,:};
