read text in matlab

To read text in Matlab, you can use the fopen() function to open the text file and create a file identifier, and then use the fscanf() function to read the contents of the file.

Here's an example code that reads a text file named data.txt, which contains one line of text:

main.m
fid = fopen('data.txt', 'r');
textData = fscanf(fid, '%c');
fclose(fid);
73 chars
4 lines

In this example, the fopen() function is used to open the data.txt file in read mode 'r', and the resulting file identifier fid is stored in a variable.

Then, the fscanf() function is used to read the contents of the file using the %c format specifier, which reads the file as a character array. The resulting text data is stored in the textData variable.

Finally, the fclose() function is used to close the file.

Note that this example reads the entire contents of the file as one string. If the file contains multiple lines of text or if you want to read numerical data, you can use different format specifiers in the fscanf() function.
