vec_arith.h File Reference


Detailed Description

Vector and matrix arithmetic.

Todo:
Properly document the operators defined as macros
Idea for future:
Define operators for complex vector * real matrix
Idea for future:
These should be replaced by the BLAS routines where possible?

    (const vec2 &x, const vec3 &y);
The header macro for vector-vector addition.

Given types vec1, vec2, and vec_3, this macro provides the function declaration for adding two vectors using the form

      vec1 operator+(const vec2 &x, const vec3 &y);

The corresponding definition is given in O2SCL_OPSRC_VEC_VEC_ADD.

By default, the following operators are defined:
