So you want to read data available in a text file and store them into some array in MATLAB, and then study to what extent these values are clustered.
See if you are able to write code for reading the text file and get the content in a MATLAB variable/array. Look at the documentation for TEXTREAD for example.

At first you have to import the values. Do you know how to use FOPEN, FSCANF and FCLOSE for importing? If not, read the corresponding help pages.
The the next step "clustering" is not uniquely defined: How do you want to find how many clusters?

You might want to look at using hist() or histc() to take the histogram of the values to see if they naturally fall into groups.
[counts, values] = hist(yourData, numberOfBins);
bar(values, counts); % Plot it.
