Hi Ekram, if you are refering to https://github.com/apache/flink/blob/d7b59d761601baba6765bb4fc407bcd9fd6a9387/flink-libraries/flink-ml/src/main/scala/org/apache/flink/ml/math/SparseMatrix.scala
You could first convert it to a Breeze Matrix: https://github.com/apache/flink/blob/1753b1d25b4d943c1ffbe7c3fb40e56b840c4f7d/flink-libraries/flink-ml/src/main/scala/org/apache/flink/ml/math/Breeze.scala#L31 and then multiply. If you are talking about a distributed matrix vectorization, you need to implement it on your own. Same applies to your question about Dense Matrices.
