NAME
     vec_$add_constant - add a scalar to a single-precision vector

SYNOPSIS (C)
     #include <apollo/base.h>
     #include <apollo/vec.h>

     void vec_$add_constant(
          float *start_vec,
          long int &length,
          float &constant,
          float *result_vec)

SYNOPSIS (Pascal)
     %include '/sys/ins/base.ins.pas';
     %include '/sys/ins/vec.ins.pas';

     procedure vec_$add_constant(
          in start_vec: univ vec_$real_vector;
          in length: integer32;
          in constant: real;
          out result_vec: univ vec_$real_vector);

SYNOPSIS (FORTRAN)
     %include '/sys/ins/base.ins.ftn'
     %include '/sys/ins/vec.ins.ftn'

           parameter (nvec = 256)

           real start_vec(nvec), result_vec(nvec), constant
           integer*4 length

           call vec_$add_constant(start_vec, length, constant, result_vec)

DESCRIPTION
     Vec_$add_constant adds the scalar constant to the single-precision vector
     start_vec, and supplies the result in result_vec.

     In C, the resulting operation is

          for (i = 0; i < length; ++i)
               result_vec[i] = constant + start_vec[i];

     In Pascal, the resulting operation is

          for i := 1 to length do
               begin
               result_vec[i] := constant + start_vec[i];
               end

     In FORTRAN, the resulting operation is

           do 10 i = 1, length
               result_vec(i) = constant + start_vec(i)
       10 continue

     start_vec
          The operand vector that constant will be added to.

     length
          The number of elements in start_vec that constant will be added to.

     constant
          A scalar constant to be added to start_vec.

     result_vec
          The vector resulting from adding constant to start_vec.

NOTES
     When vec_$add_constant is used to operate on matrixes in C and Pascal,
     start_vec and result_vec are row vectors; whereas in FORTRAN, they are
     column vectors.
