Class  Description 

AMAX 
Given a vector x, the i?amax functions return the position of the vector element x[i] that has the largest
absolute value for real flavors, or the largest sum Re(x[i])+Im(x[i]) for complex flavors.

AMIN 
Given a vector x, the i?amin functions return the position of the vector element x[i] that has the smallest
absolute value for real flavors, or the smallest sum Re(x[i])+Im(x[i]) for complex flavors.

ASUM 
The ?asum routine computes the sum of the magnitudes of elements of a real vector, or the sum of magnitudes
of the real and imaginary parts of elements of a complex vector: res = Re x1 + Im x1 + Re x2 + Im
x2+ ...

AXPY 
The ?axpy routines perform a vectorvector operation defined as y := a*x + y where: a is a scalar x and y
are vectors each with a number of elements that equals n.

CABS1 
The ?cabs1 is an auxiliary routine for a few BLAS Level 1 routines.

COPY 
The ?copy routines perform a vectorvector operation defined as y = x, where x and y are vectors.

DOT 
The ?dot routines perform a vectorvector reduction operation defined as Equation where xi and yi are
elements of vectors x and y.

DOTC 
The ?dotc routines perform a vectorvector operation defined as: Equation

DOTU 
The ?dotu routines perform a vectorvector reduction operation defined as Equation where xi and yi are
elements of complex vectors x and y.

NRM2 
The ?nrm2 routines perform a vector reduction operation defined as res = x, where: x is a vector, res
is a value containing the Euclidean norm of the elements of x.

ROT 
Given two complex vectors x and y, each vector element of these vectors is replaced as follows: xi = c*xi +
s*yi yi = c*yi  s*xi

ROTG 
Given the Cartesian coordinates (a, b) of a point, these routines return the parameters c, s, r, and z
associated with the Givens rotation.

ROTM 
Given two vectors x and y, each vector element of these vectors is replaced as follows: for i=1 to n, where
H is a modified Givens transformation matrix whose values are stored in the param[1] through param[4]
array.

ROTMG 
Given Cartesian coordinates (x1, y1) of an input vector, these routines compute the components of a
modified Givens transformation matrix H that zeros the ycomponent of the resulting vector:

SCAL 
The ?scal routines perform a vector operation defined as x = a*x where: a is a scalar, x is an nelement
vector.

SDOT 
The ?sdot routines compute the inner product of two vectors with double precision.

SWAP 
Given two vectors x and y, the ?swap routines return vectors y and x swapped, each replacing the other.
