MATRIX("SIGNATURE",order)
- is the size of the Signature matrix.
is the size of the Signature matrix.Description
- This function returns the matrix of order 3 with the property of signature matrix.
- A signature matrix is a diagonal elements are
- So signature matrix is of the form:
- Any such matrix is its own inverse, hence is an involutory matrix.
- It is consequently a square root of the identity matrix.
- Also that not all square roots of the identity are signature matrices.
- The signature matrices are both symmetric and involutory,i.e.,they are orthogonal.
- Consequently, any linear transformation corresponding to a signature matrix constitutes an isometry.
