MATLAB: Using textscan

text filetextscan

Is textscan the correct command to use when importing data from text files into matlab. The command seems to work fine if I only have a vector in the text file, but if I have a matrix, matlab will change the structure of the data and store the matrix as a vector. Which command should I use if I'm importing data from text files within a loop where some of the text files include vectors and others include matrices?

You have to specify the right 'format', read example 8 to get an idea: http://www.mathworks.co.uk/help/techdoc/ref/textscan.html

Use fopen to open the file and then use fscanf or fgetl to read in the content. You can also use fread. For example, the following code reads the first line of the text.

fid = fopen(v,'r');
tline = fgetl(fid);
fclose(fid)

Just to remember close the file using fclose afterwards.

doc fopen
doc fclose
doc fread
doc fscanf
doc fgetl

MATLAB: Issue with data format when using textscan()

The format should be all lower case for duration.

%{hh:mm:ss}T

However, the data appears to be delimited as semicolon. You'd have more luck with readtable:

opts = detectImportOptions('D:\SI010118.txt')
opts = setvartype(opts,1,'datetime')
opts = setvaropts(opts,1,'InputFormat','dd.MM.uuuu HH:mm:ss')
readtable('D:\SI010118.txt',opts)
