Matrix-exponentiation operator: Difference between revisions

Wren's Num class uses a method (pow) rather than an operator for exponentiation.

The Matrix class in the above module also has a 'pow' method but, as an alternative, overloads the otherwise unused '^' operator to provide the same functionality.

<lang ecmascript>import "/matrix" for Matrix

import "/fmt" for Fmt

var m = Matrix.new([[0, 1], [1, 1]])

System.print("Original:\n")

Fmt.mprint(m, 2, 0)

System.print("\nRaised to power of 10:\n")

Fmt.mprint(m ^ 10, 3, 0)</lang>

Original:

Raised to power of 10:
