Convert Matrix to RowMatrix in Apache Spark using Scala

Question

I\'d really like to convert my org.apache.spark.mllib.linalg.Matrix to org.apache.spark.mllib.linalg.distributed.RowMatrix

I can do it as such:

val         


        

Answer 1

small correction in above code: we need to use Vectors.dense instead of new DenseVector

val vectors = rows.map(row =>  Vectors.dense(row.toArray))
