Data type conversions

GSL to NArray


  • GSL::Vector#to_na
  • GSL::Vector#to_nvector
  • GSL::Vector::Complex#to_na
  • GSL::Vector::Complex#to_nvector
  • GSL::Matrix#to_na
  • GSL::Matrix#to_nmatrix

    Convert GSL objects to NArray. The data contained by the GSL objects are copied to a newly allocated memory block of the NArray objects created.


  • GSL::Vector#to_na_ref
  • GSL::Vector#to_nvector_ref
  • GSL::Vector::Complex#to_na_ref
  • GSL::Vector::Complex#to_nvector_ref
  • GSL::Matrix#to_na_ref
  • GSL::Matrix#to_nmatrix_ref

    Create NArray-ref objects from GSL data. The memory block of the GSL objects are shared with the NArray-ref objects.

    Example:

      >> v = Vector::Int[0..5]
      => GSL::Vector::Int
      [ 0 1 2 3 4 5 ]
      >> na = v.to_nvector_ref
      => NVector(ref).int(6):
      [ 0, 1, 2, 3, 4, 5 ]
      >> na[3] = 999
      => 999
      >> v
      => GSL::Vector::Int
      [ 0 1 2 999 4 5 ]
    

NArray to GSL


  • NArray#to_gv
  • NArray#to_gm

    NArray#to_gv converts NArray objects to GSL::Vector or GSL::Vector::Complex. NArray#to_gm converts NArray objects to GSL::Matrix. The data contained by the NArray objects are copied to a newly allocated memory block of the GSL objects created.


  • NArray#to_gv_view
  • NArray#to_gm_view

    Create GSL::Vector::View or GSL::Matrix::View objects from NArray. The memory block of the NArray objects are shared with the View objects.

    Example:

      >> na = NArray[0, 1, 2, 3, 4, 5]
      => NArray.int(6):
      [ 0, 1, 2, 3, 4, 5 ]
      >> b = na.to_gv_int_view
      => GSL::Vector::Int::View
      [ 0 1 2 3 4 5 ]
      >> b[2] = -99
      => -99
      >> na
      => NArray.int(6):
      [ 0, 1, -99, 3, 4, 5 ]
