fid = fopen('YourFile.txt', 'rt');
data_cell = textscan(fid, '%*s%*s%*s%f', 'Delimiter', '\t');
fclose(fid)
data = data_cell{1};

You can use the "readtable" function to import your data. See the documentation below:
You can use something like the following command:
>> T = readtable('data.txt','Delimiter',' ','ReadVariableNames',false);
In the command above, I'm assuming that, 1. Your data is in a file named data.txt 2. Your data is delimited by a space 3. Your data file does not include headers
After you read the data into a table, you can access each element as necessary. If you only need the last column, you can do something like the following:
>> T = T(:, end);

The posted line turns out to be delimited by tabs, at least as posted. For that you would use 'Delimiter', '\t'
