Is this a question about how to classify the data based on threshold?
if condition
"classification description"
else
"classification description"
end
can be a solution.

Do you want to use fixed some points as centroids of the clusters?
OK, you've got an algorithm?
Then, is your question how to put the algorithm into practice in MATLAB?
Your algorithm sounds very straightfoward. It seems it is just a matter of how to write it in MATLAB. Am I right?
If so, you should start from basics: https://matlabacademy.mathworks.com/
MATLAB onramp is a good fit for you.

As far as I know, the centroids of clusters are determined by the corresponding clusters. So it is uncommon to fix the centroids before finding the clusters.
I suppose you can write by yourself. It sounds very easy.
Algorithm as follows:
- calculate the distances from all the centroids
- classify the data into the nearest cluster
- loop 1 and 2 till end
