=====sum=====

Calculate the summation over one or more user-defined extents of a vector <var>x</var>. The result of the following functions is a vector or a scalar (depending on the number of extents).

The summation of <var>n</var> extents of <var>x</var>. The first extent begins with the index <var>u</var>s and the last extent ends with the index <var>o</var>s.

=====Usage:=====

<code>sum(<var>x</var>, <var>u</var>s, <var>o</var>s, <var>n</var>)</code>

=====Result:=====

If <var>n</var> > <code>1</code> the result is a vector, otherwise it is a scalar.

The summation over the extent nrow(<var>u</var>v). Every pair (<var>u</var>v[i], <var>o</var>v[i]) defines an index extent to sum.

=====Usage:=====

<code>sum(<var>x</var>, <var>u</var>v, <var>o</var>v)</code>

The summation over the extent nrow(<var>r</var>v)-1. Every pair (<var>r</var>v[i], <var>r</var>v[i+1]) defines an index extent to sum.

=====Usage:=====

<code>sum(<var>x</var>, <var>r</var>v)</code>

The summation over the extent nrow(<var>r</var>m). Every pair (<var>r</var>m[i,0], <var>r</var>v[i,1] defines an index extent for summation.

=====Usage:=====

<code>sum(<var>x</var>, <var>r</var>m)</code>
