f2c.h

完全使用C++写的高效线性代数运算库！还提供了矩阵类。

/*
// NOTE: this is a modified file of f2c.h to work with most C++ compilers.
//       f2c.h for example, defines abs() as a macro, casuing parsing
//       problems when it encounters abs() in stdlib.h, and so on.
//       It is needed in Lapack++ because some of the C/Lapack functions, like
//       ilaenv_(), need to know what ftn_len is (system dependent.)
//
//       pow_ri() has been removed, since it collides with
//       sunmath.h on SUN4s.
//
//        "typedef float real" has been removed, due to conflict with
//        AT&T CC with real() for complex.
//
//        "typedef ... complex" has been renamed to f2c_complex to
//        avoid conflicts with C++ complex class.
