Hadamard Product (Element-wise) Calculator

Compute the Hadamard product (element-wise product) of two same-size matrices. Enter each row and get the result matrix as a table.

Input

Enter two matrices, one row per line. Separate entries with spaces or commas (each line = one matrix row).

The Hadamard product (symbol ⊙), also called the element-wise or Schur product, takes two matrices A and B of the same size and multiplies entries in matching positions. Its (i, j) entry is A(i, j) times B(i, j).
The Hadamard product is defined only when both matrices have exactly the same dimensions (same number of rows and columns). Matrices of different sizes cannot be combined this way.
It is different from the standard matrix product (A×B). The matrix product is defined when the number of columns of A equals the number of rows of B and forms entries from dot products, so its size and entries differ from the Hadamard product.
Each input line is treated as one row of the matrix, with entries separated by spaces or commas. Blank lines are ignored.
The Hadamard product is commutative (A⊙B = B⊙A). Because it is a simple position-by-position multiplication, it is widely used for masking in image processing and element-wise operations in machine learning.
