Determines whether a matrix is of one of the following special types: symmetric positive definite, symmetric positive semi-definite, symmetric, or Hermitian.

datatype_icon

input matrix

The matrix that you want to test for special type.

Default: Empty array

datatype_icon

matrix type

The type you want to compare to the type of input matrix.

Symmetric Positive Definite 10 Determines whether input matrix is symmetric positive definite.
Symmetric Positive Semi-Definite 11 Determines whether input matrix is symmetric positive semi-definite.
Symmetric 20 Determines whether input matrix is symmetric.
Hermitian 21 Determines whether input matrix is Hermitian.

Default: 10—Symmetric Positive Definite

datatype_icon

relative tolerance

A value that determines how close input matrix must be to the specified special type.

The exact meaning of this input depends on the value of matrix type.

If relative tolerance is less than 0, this node chooses a tolerance based on input matrix.

Default: -1

datatype_icon

is type?

A Boolean that indicates whether input matrix is the same type as matrix type. Is TRUE if input matrix is a matrix of special type. Otherwise, is type? is FALSE.

TRUE The type of input matrix matches matrix type.
FALSE The type of input matrix does not match matrix type.
datatype_icon

error

A value that represents any error or warning that occurs when this node executes.
