Macro Definition Documentation

ROT

#define ROT	(		A,
			i,
			j
	)

Value:

    { \
      double * __restrict__ ai = &A(i,0); \
      double * __restrict__ aj = &A(j,0); \
      for (k=0; k<n; k++) { \
          double t = ai[k]; \
          double u = aj[k]; \
          ai[k] = c*t - s*u; \
          aj[k] = s*t + c*u; \
      } \
    }

ROTT

#define ROTT	(		A,
			i,
			j
	)

Value:

    { \
      double * __restrict__ ai = &A(0,i);      \
      double * __restrict__ aj = &A(0,j);       \
      for (k=0; k<n*n; k+=n) { \
          double t = ai[k]; \
          double u = aj[k]; \
          ai[k] = c*t - s*u; \
          aj[k] = s*t + c*u; \
      } \
    }
