linalg_create¶

Contains functions and subroutines to create objects with certain properties.

linalg_create_arrays¶

Contains functions and subroutines to create arrays with different shapes and properties.

Function: linspace¶

Returns a one-dimensional array \(y(num)\) with evenly spaced numbers over the interval \([a,b]\).

function linspace(a, b, num) result(y)
  real(wp), intent(in) :: a
  real(wp), intent(in) :: b
  integer, intent(in) :: num
  real(wp), dimension(num) :: y
end function linspace

linalg_matrices¶

Contains functions and routines for matrix operations.

linalg_matrices_inverse¶

Contains functions to compute the inverse of a matrix.

Function: inversereal¶

Returns the inverse \(a^{-1}\) of a real matrix \(a\).

function inversereal(a) result(ainv)
  real(kind=wp), intent(in) :: a(:,:)
  real(kind=wp) :: ainv(size(a,1),size(a,2))
end function inversereal

Function: inversecomplex¶

Returns the inverse \(a^{-1}\) of a complex matrix \(a\).

function inversecomplex(a) result(ainv)
  complex(wp), intent(in) :: a(:,:)
  complex(wp) :: ainv(size(a,1),size(a,2))
end function inversecomplex
