Collaboration diagram for Level 1 BLAS: vector ops:

Modules
	asum: sum \| real( x_i ) \| + \| imag( x_i ) \|

	sum1: sum \| x_i \| (in LAPACK)

	axpy: y = ax + y

	copy: y = x

	dot: x^H x and x^T x

	iamax: argmax_i \| real( x_i ) \| + \| imag( x_i ) \|

	imax1: argmax_i \| x_i \| (in LAPACK)

	nrm2: \|\| x \|\|_2

	scal: x = alpha x

	swap: x <=> y

	— Givens/Jacobi plane rotations —

	rot: apply plane rotation ([cz]rot in LAPACK)

	rotg: generate plane rotation (cf. lartg)

	rotm: apply modified (fast) plane rotation

	rotmg: generate modified (fast) plane rotation
