The Hadamard product – also known as the element-wise product or entrywise product.

Alaa H Lafta

Many thanks dear sir.

Debopam Ghosh

In this context, you can also have a look into Khatri -Rao Matrix product and the Face Splitting product.

Vladimir Kornyak

The Hadamard product is "entry by entry" product, not the asked "row by row", which is the stadard matrix multiplication with transposed second matrix.
