HadamardBoundSq    --    Hadamard bound for determinant


Syntax
HadamardBoundSq(M: MAT): RECORD

Description
This computes square of the Hadamard determinant bound (both for rows and for columns). The result is a record with two fields ColBoundSq and RowBoundSq. An error is signalled if M is not square.

The field names were changed in version 5.4.2.

Example
/**/  M := mat([[1,2],[3,4]]);
/**/  HadamardBoundSq(M);
record[ColBoundSq := 200, RowBoundSq := 125]
