- NAME:
*add_apply_vector* - SYNOPSIS:
*INT add_apply_vector(OP a,b)* - DESCRIPTION:
*a,b*should be two VECTORobjects, and the routine computes*b = b+a,*where the addition of the two vectors is componentwise. This also works, if the VECTORobjects have different length.*a,b*must be different objects. - RETURN: OK, or ERROR if some error occured.
- BUG: there is no check on types, because this is a special
routine, normally you should use
*add_apply*instead.

- NAME:
*add_vector* - SYNOPSIS:
*INT add_vector(OP a,b,c)* - DESCRIPTION:
*a,b*should be VECTORobjects,*c*should be an empty object. The routine computes*c = a+b.*The addition is componentwise, and it also works if the vectors have different length.*a,b,c*must all be different - RETURN: OK, or ERROR
- BUG: there is no check on types, because this is a special routine, normally you should use add instead.

- NAME:
*addinvers_apply_vector* - SYNOPSIS:
*INT addinvers_apply_vector(OP a)* - DESCRIPTION:
*a*should be a VECTORobject. The routine computes*a = -a.*This is also meant componentwise. - RETURN: OK, or ERROR
- BUG: there is no check on types, because this is a special
routine, normally you should use
*addinvers_apply*instead.

- NAME:
*addinvers_vector* - SYNOPSIS:
*INT addinvers_vector(OP a,b)* - DESCRIPTION:
*a*should be a VECTORobject.*b*should be an empty object. The routine computes*b = -a.*This is meant componentwise. - RETURN: OK, or ERROR
- BUG: there is no check on types, because this is a special
routine, normally you should use
*addinvers*instead.

- NAME:
*addtoallvectorelements* - SYNOPSIS:
*INT addtoallvectorelements(OP a,b,c)* - DESCRIPTION:
*b*should be a vector, the routine adds*a*to all the elements of*b,*the result will become*c.* - RETURN: OK or ERROR.
- BUG: it only works for different
*a,b,c*

- NAME:
*mult_scalar_vector* - SYNOPSIS:
*INT mult_scalar_vector(OP a,b,c)* - DESCRIPTION:
*b*should be a VECTORobject,*c*should be an empty object. The routine multiplies each element of*b*by*a,*and the result is*c.* - RETURN: OK, or ERROR
- BUG: there is no check on types, because this is a special
routine, normally you should use
*mult*instead.

- NAME:
*mult_apply_vector_vector* - SYNOPSIS:
*INT mult_apply_vector_vector(OP a,b)* - DESCRIPTION:
*a,b*should be VECTORobjects, The routine multiplies componentwise, and the result is*b.*The vectors must be of the same length. - RETURN: OK, or ERROR
- BUG: there is no check on types, because this is a special
routine, normally you should use
*mult_apply*instead.

- NAME:
*mult_vector_matrix* - SYNOPSIS:
*INT mult_vector_matrix(OP a,b,c)* - DESCRIPTION:
*a*should be a VECTORobject,*b*should be a MATRIX object,*c*should be an empty object. The routine multiplies according to the rules for the multiplication of matrices, and the result becomes a VECTORobject. The length of the VECTORobject a must be equal to the height of the MATRIX object*b.* - RETURN: OK, or ERROR
- BUG: there is no check on types, because this is a special
routine, normally you should use
*mult*instead.

- NAME:
*mult_vector_vector* - SYNOPSIS:
*INT mult_vector_vector(OP a,b,c)* - DESCRIPTION:
*a,b*should be VECTORobjects,*c*should be an empty object. The routine multiplies componentwise, and the result is*c.*The vectors must be of the same length. - RETURN: OK, or ERROR
- BUG: there is no check on types, because this is a special
routine, normally you should use
*mult*instead.

- NAME:
*scalarproduct_vector* - SYNOPSIS:
*INT scalarproduct_vector(OP a,b,c)* - DESCRIPTION:
*a,b*should be VECTORobjects,*c*should be the empty object.*a*and*b*must have the same length.*c*becomes the euclidian scalarproduct of*a*and*b.* - RETURN: OK, or ERROR
- BUG: there is no check on types, because this is a special
routine, normally you should use
*scalarproduct*instead.

- NAME:
*sum_vector* - SYNOPSIS:
*INT sum_vector(OP a,b)* - DESCRIPTION:
*a*should be a VECTORobject,*b*should be the empty object.*b*becomes the sum over the vector*a.* - RETURN: OK, or ERROR
- BUG: there is no check on types, because this is a special
routine, normally you should use
*sum*instead.
