MATLAB: Tables automatic import from txt

importMATLABmatrixmatrixestabletablestxt

Hi everyone,

I have a file .txt with several tables (written like columns of numbers separated by spaces) and phrases that separate them and the tables have different dimensions. I need to import them separately in Matlab using a script that reads the .txt file and automatically recognize the tables and import them, or that imports everything and then automatically recognizes the matrixes I need.

Someone knows how can I do it?

Best Answer

use readtable() to read the text file

Read it using these lines

filetxt = fileread('m1.txt');
filetxt = strrep(filetxt, ',', '.');
data = cell2mat(textscan(filetxt, '%f%f%f%f'))

You can use readtable() and convert to timetable() objects, and use timerange() indexing.

Alternately, you can use readtable(), and use month() on the date column, and compare the result to 3 in order to get a mask for which rows to use. Note that this would find all March items from separate years if there are multiple years in the file.
