HadamardMatrix
HadamardMatrix[n]
returns an n×n Hadamard matrix.
Details and Options
- Each entry
of the Hadamard matrix is by default defined as 
, where 
, 
is the 
bit in the binary representation of the integer 
, and 
. - Rows or columns of the HadamardMatrix are basis sequences of the discrete Hadamard transform.
- A Hadamard matrix is its own inverse.
- HadamardMatrix takes an option
. Sequency is the number of zero crossings of the Hadamard basis sequences. The default is "SequencyOrdered"->True where the sequency increases with row or column index. With "SequencyOrdered"->False, 
. - HadamardMatrix[..., WorkingPrecision->p] gives a matrix with entries of precision p.
