Hi all,
I have to read the file (inserted in attachment) and only need the numeric portion as a matrix(array). The extension of file is .TXK .
Thanks in advance

You could use the readmatrix function as follows:
filename = 'My2.TXK'
opts = detectImportOptions(filename,'FileType','text')
data = readmatrix(filename,opts)
the .TXK extension is not recognised by readmatrix which is why I specified the FileType as text in the import options.
You could optionally read in as a table:
T = readtable(filename,opts)
If you want to get the variable names automatically, for example if you have a number of similar data files, I would need to see what the first line of text looks like generally across the files.

Should work in R2016a:
filename = 'My2.TXK'; %using full path would be better
[fid, errmsg] = fopen(filename, 'rt');
assert(fid > 0, 'Failed to open "%s" due to error: %s', filename, errmsg);
data = cell2mat(textscan(fid, '%f%f%f', 'Delimiter', {'\t', ' '}, 'MultipleDelimsAsOne', true, 'HeaderLines', 1));
