<h2>Description</h2>
<p>Define a computation that extracts the improper energy calculated by
each of the improper sub-styles used in the <a class="reference internal" href="improper_hybrid.html"><span class="doc">improper_style hybrid</span></a> command. These values are made
accessible for output or further processing by other commands. The
group specified for this command is ignored.</p>
<p>This compute is useful when using <a class="reference internal" href="improper_hybrid.html"><span class="doc">improper_style hybrid</span></a> if you want to know the portion of the
total energy contributed by one or more of the hybrid sub-styles.</p>
<p><strong>Output info:</strong></p>
<p>This compute calculates a global vector of length N where N is the
number of sub_styles defined by the <a class="reference internal" href="improper_style.html"><span class="doc">improper_style hybrid</span></a> command. which can be accessed by indices
1-N. These values can be used by any command that uses global scalar
or vector values from a compute as input. See <a class="reference internal" href="Section_howto.html#howto-15"><span class="std std-ref">this section</span></a> for an overview of LAMMPS output
options.</p>
<p>The vector values are &#8220;extensive&#8221; and will be in energy
