  • Assignment of differently dimensioned array supported to facilitate storing STL containers of FArrays
  • Cross product functions added for FArray1D
  • New FArray2D functions:
    • identity: Named identity matrix constructor
    • to_identity: Converts to identity matrix
    • diag:  Named diagonal matrix constructor
    • to_diag:  Converts to a diagonal matrix

ObjexxFCL 2.4.0

• FArray:
  • Data-preserving redimension functions added for real FArrays
  • swap functions added for real FArrays
  • Initializer set and clear functions added for real FArrays
  • Copy constructor template variants made explicit to prevent unintended copying

  • Implemented as std::vector< Chunk >
  • Chunk is now an efficient growable array with controllable capacity
  • Constructor that doesn't initialize built-in C++ value types is available for performance
  • std::vector interoperation
  • push_back, pop_back, resize, shrink, and swap operations support efficient dynamic growth

  • Exponent argument must be specified as an unsigned value or ChunkExponent( x ) to disambiguate some ChunkVector function calls
• Dimension expression functions added: min, max, square, cube, and pow

ObjexxFCL 2.3.4

• Refined/extended string_of and Fstring_of functions
• Added FArray assign functions that redimension if necessary and assign another array's values
• Microsoft® Visual C++ 7.1 compatibility added

ObjexxFCL 2.3.3

• Windows and Linux 64-bit platform compatibility and large array support

• rvalue_cast template function added

ObjexxFCL 2.3.1

• Eliminated convenience header inclusions for finer-grained inclusion control and faster builds
