- Identity[Order n]
- Returns the identity matrix with the given order
- Example:
Identity[3]gives you the matrix {{1, 0, 0}, {0, 1, 0}, {0, 0, 1}}.
- Note: If A is a square matrix of order n,
A^0produces the same matrix asIdentity[n].
CAS Specific Syntax
- Identity[Order n]
- Returns the identity matrix with the given order.
