MatrixUDT and VectorUDT in Spark ML

Hi All, I came across these two types MatrixUDT and VectorUDF in Spark ML when doing feature extraction and preprocessing with PySpark. However, when trying to do some basic operations, such as vector multiplication and matrix multiplication, I had to go down to Python UDF. It seems to be it woul
