trace Interface

public interface trace

This interace overloads the trace interface from stdlib_linalg to compute the trace of a Poisson2D matrix .

Syntax

   tr = trace(A)

Arguments

  • A : Matrix of Poisson2D type. It is an intent(in) argument.

  • tr: Trace of the matrix.


Functions

private pure module function trace_rdp(A) result(tr)

Arguments

Type IntentOptional Attributes Name
type(Poisson2D), intent(in) :: A

Input matrix.

Return Value real(kind=dp)

Trace of the matrix.
