*<math>order</math> is the order of the hadamard matrix.
==Description==
*This function gives the matrix satisfying the property of Hadamard.
*A Hadamard matrix is the square matrix with the entries of 1 and -1.
*Also the rows of that matrix are orthogonal.Let H be a Hadamard matrix of order n.
*The transpose of H is closely related to its inverse.
*The equivalent definition for hadamard matrix is:
<math>H H^{T} = n I_{n}</math>
where <math>I_{n}</math> is the n × n identity matrix and <math>H^T</math> is the transpose of H.
*So the possible order of the matrix is 1,2 or positive multiple of 4.
*The examples of hadamard matrices are:
