Hi, I need a matrix with each row having a index, e.g., index = 0 for first row, index = 1 for second row. Could someone tell me how to generate such IndexedRowMatrix from an RowMatrix? Besides, is there anyone having the experience to do multiplication of two distributed matrix, e.g., two RowMatrix? thank you!
