K means algorithm in matlab
WebJan 2, 2024 · K-Means To calculate the distance you shouldn't use repmat () which will allocate new memory. To calculate the Distance Matrix with the 3rd dimension and broadcasting you should do something like: mD = sum ( (reshape (mA, numVarA, 1, varDim) - reshape (mB.', 1, numVarB, varDim)) .^ 2, 3); But a faster way would be: WebK Means Algorithm in Matlab For you who like to use Matlab, Matlab Statistical Toolbox contain a function name kmeans . If you do not have the statistical toolbox, you may use my generic code below. The latest code of kMeanCluster and distMatrix can be downloaded here . The updated code can goes to N dimensions.
