Utility Functions

 

GRAPE provides some useful utility functions that are frequently used. Included are not only mathematical utility functions, but also routines for:

• memory management,
• vector calculations (VEC2, VEC3, VEC4 and n_dim vectors) and
• matrix operations

Furthermore a number of complex functions that are available in GRAPE simplify the handling of complex variables.

• Memory Functions
  • Basic Memory Functions
  • Fast Functions for Large Numbers of Small Blocks
  • Functions for allocating/freeing memory of data-arrays
  • Functions for allocating/freeing memory of pointer-arrays
  • Functions for allocating/freeing memory of arrays of GRAPE datatypes
• Functions on VEC2
• Functions on VEC3
• Functions on VEC4
• Matrix Functions
• Functions for Arrays and n-dim Vectors
• Transformation Functions
• Function Interpreter Functions
• String Functions
• Method String Functions
• Swap Functions
• Drawing Routines
• Time Functions
• General Utility Macros
• Math Utility Functions
• Functions for Triang2d
• Complex Functions
  • Complex Constants
  • Complex Functions with one Complex Argument
  • Complex Functions with two Complex Arguments
  • Complex Functions with one Complex and one Real Argument
  • Other Complex Functions
