Implements DetRootN
.
Classes
- class picos.expressions.exp_detrootn.DetRootN(x)[source]¶
Bases:
Expression
The
-th root of the determinant of an
matrix.
- Definition
For an
positive semidefinite hermitian matrix
, this is
Warning
When you pose a lower bound on the
-th root of a determinant of the matrix
, then PICOS enforces positive semidefiniteness
through an auxiliary constraint during solution search.
- __init__(x)[source]¶
Construct a
DetRootN
.- Parameters
x (ComplexAffineExpression) – The matrix concerned. Must be hermitian by definition.
- property x¶
The matrix concerned.
