How to read formatted data containing spaces in matlab using textscan function

1. How does textscan in MATLAB read formats containing spaces?

In MATLAB, if you want to use the textscan function to read the format containing spaces, you can use the format specifier %q to read the quoted format String, where spaces are preserved. The following is a simple example:

fid = fopen('example.txt', 'r');
data = textscan(fid, '%s %s', 'Delimiter', ',');
fclose(fid);

% 输出读取到的数据
disp(data);

In the above example, assume that the file example.txt contains the following content:

str = 'Hello World';
parts = strsplit(str, ' ');
disp(parts);

2. Use the index to get the substring:

str = 'MATLAB';
sub = str(2:4);
disp(sub);

3. Use the strrep function to replace the content in the string:

str = 'apple orange apple';
newStr = strrep(str, 'apple', 'banana');
disp(newStr);

4. Use regular expression to replace:

str = 'The quick brown fox';
newStr = regexprep(str, 'brown', 'red');
disp(newStr);

5. Use sprintfFunction format string:

name = 'John';
age = 25;
formattedStr = sprintf('Name: %s, Age: %d', name, age);
disp(formattedStr);

Summary:

1. (1) in MATLAB When using the textscan function to read a format containing spaces, you can use %q to read a quoted string, retaining spaces.

2. (2) String splitting and modification can use strsplit, index to obtain substrings, strrep function replacement, regular expressions Replacement, sprintf function formatting and other methods, choose the appropriate operation according to specific needs.
