Function Documentation

void meml_vector_clear ( VECTOR * x )

$ x :=0 $

INLINE int meml_vector_element_add ( VECTOR * x,

const MEML_INT i,

const MEML_FLOAT value

)

x[i] := x[i] + value

INLINE void meml_vector_element_add_f ( VECTOR * x,

const MEML_INT i,

const MEML_FLOAT value

)

x[i] := x[i] + value

INLINE MEML_FLOAT meml_vector_element_get ( const VECTOR * x,

const MEML_INT i

)

alpha := x[i]

INLINE MEML_FLOAT meml_vector_element_get_f ( const VECTOR * x,

const MEML_INT i

)

alpha := x[i]

INLINE int meml_vector_element_set ( VECTOR * x,

const MEML_INT i,

const MEML_FLOAT value

)

x[i] := value

INLINE void meml_vector_element_set_f ( VECTOR * x,

const MEML_INT i,

const MEML_FLOAT value

)

x[i] := value

INDEXARRAY* meml_vector_part_sort ( VECTOR * v,

MEML_INT from,

MEML_INT till

)

sorts a part of the vector v; v[from:till] ; ascending
The INDEXARRAY which the function returns shows where the single element has been moved.
e.g. v = [ 4 2 1 3] ; form = 0 ; till = 3
after calling meml_vector_part_sort_f it will look like this:
v = [1 2 3 4] ; indexarray = [ 3 1 0 2]
so you see, v[0] has been moved to v[3] etc.

VECTOR* meml_vector_scaling ( const MEML_FLOAT alpha,

const VECTOR * x

)

$y := \alpha x$

INDEXARRAY* meml_vector_sort ( VECTOR * v )

sorts a vector v ascending
The INDEXARRAY which the function returns shows where the single element has been moved.
e.g. v = [ 5.10e+00 2.21e+00 4.54e+00 1.00e-01 8.10e+00 ]
after calling meml_vector_part_sort it will look like this:
v = [ 1.00e-01 2.21e+00 4.54e+00 5.10e+00 8.10e+00 ] indexarray = [ 3 1 2 0 4 ]
so you see, v[0] has been moved to v[3] etc.
