MATRIX("MONOMIAL",order)
- is the order of the Monomial matrix.
is the order of the Monomial matrix.Description
- This function gives the matrix of order 3 with the property of monomial matrix.
- A monomial matrix is a square matrix with exactly one nonzero entry in each row and exactly one nonzero entry in each column.
- So here MATRIX("monomial") is showing the monomial matrix of order 3.
- Monomial matrix is also called as generalized permutation matrix.
- So in Calci, users can give the argument as MATRIX("Monomial") or MATRIX(" generalized permutation").
- An example of monomial or generalized permutation matrix is:
- So any monomial matrix is the product of a permutation matrix and a diagonal matrix.
Examples
- 1.MATRIX("Monomial")=1
