hadamard -- computes the Hadamard product of two matrices

Synopsis

Description

This method computes the Hadamard product of two matrices A, B of the same size. The Hadamard product is defined as the componentwise product, i.e., if A, B are m×n matrices, then the Hadamard product is the m×n matrix with (i,j) entry equal to Ai,j*Bi,j.

i1 : (A1, A2) = (random(ZZ^2, ZZ^3), random(ZZ^2, ZZ^3))

o1 = (| 8 3 8 |, | 3 8 5 |)
      | 1 7 3 |  | 7 8 7 |

o1 : Sequence
i2 : hadamard(A1, A2)

o2 = | 24 24 40 |
     | 7  56 21 |

              2        3
o2 : Matrix ZZ  <--- ZZ
