Looks like you have multiple "kmeans" on the path.

which kmeans -all

Probably rename the kmeans.m from the path in your question?

MATLAB: What is the toolbox for kmeans

The kmeans function is in Statistics and Machine Learning Toolbox (previously the Statistics Toolbox) and has been since at least release R2006a. Do you have this toolbox both installed and licensed? [If you're in an environment where you share licenses with others in your institution, all the licenses may be in use when you try to use kmeans.]

Can you clarify what you mean by "Matlab[sic] doesn't find kmeans as a function"? Does it throw an error (and if so what is the full and exact text of that error -- show us all the text displayed in red?) Does it issue a warning? Does it do something else?

MATLAB: K means

Note that your setup code is equivalent to

ab = double(img(:));

You are passing in a single column of data to kmeans(), so kmeans is getting 1D data, but you are trying to initialize the centroids as a pair of two-dimensional points.
