orthog

  

test for orthogonal matrices

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

orthog(A)

Parameters

A

-

square matrix

Description

• 

Important: The linalg package has been deprecated. Use the superseding command LinearAlgebra[IsOrthogonal], instead.

  

- For information on migrating linalg code to the new packages, see examples/LinearAlgebraMigration.

• 

The function orthog returns true if it can show that the matrix A is orthogonal, false if it can show that the matrix is not orthogonal, and FAIL otherwise.

• 

A matrix is orthogonal if the inner product of any column of A with itself is 1, and the inner product of any column of A with any other column is 0.

• 

The Maple function testeq is used to test whether expressions are equivalent to 0 or 1.

• 

The command with(linalg,orthog) allows the use of the abbreviated form of this command.
