If you are using http://www.mathworks.com/help/stats/kmeans.html then use the Start option and supply the matrix of centroids.

[Walter Roberson]

opts = statset('Start',rand(7,3));
kmeans(TheData, opts)

Thank you for answer but With the implementation of the first line gives the following error: ??? Error using ==> statset at 267 Unrecognized parameter name 'Start'.

Perhaps you have an old version. What does it say about MATLAB's version and toolboxes when you issue the "ver" command? Do you have the Statistics Toolbox installed?
