If your text file contains uniform data (all of the same type), you can import the data as a matrix. Importing your data into a matrix allows you to work with a minimally formatted array. Import tabular data from a text file into a matrix using readmatrix.

Nov 5, 2014 · I have a formatted text file (attached). I have to read it, ignoring some bits like the headings. After reading I should be able to get tx=2

You can export tabular data from MATLAB® workspace into a text file using the writetable function. Create a sample table, write the table to text file, and then write the table to text file with additional options.

A = fscanf(fileID,formatSpec) reads data from an open text file into column vector A and interprets values in the file according to the format specified by formatSpec. The fscanf function reapplies the format throughout the entire file and positions the file pointer at the end-of-file marker.

The simplest way to store results from a MATLAB program is to write the value of one or more variables to a file using the save command. Executing save with no arguments saves the contents of the entire workspace to a file called matlab.mat. This is a binary file format that can only be read by MATLAB.

Feb 16, 2015 · Hi, I am trying to save the values in a variable to a text file. I used "-ascii" with the save command but the values in the text file are different from the one present in d variable. temp_var=1000; save mat_to_text.txt '-ASCII'temp_var
