Expand All Parameter Permutations

Sometimes one may want the result as a function of one or more values. In order to get a grid of all permutations you my use this expandset.xsl template.

This template takes a source file of the form:

<?xml version="1.0" encoding="UTF-8"?>
<setup>
  <param name="gmaxvr">
    <val>7</val>
    <val>8</val>
    <val>9</val>
  </param>
  <param name="rgkmax">
    <val>11</val>
    <val>12</val>
  </param>
  <param name="swidth">
    <val>0.001</val>
    <val>0.002</val>
  </param>
  <param name="spinpol">
    <val>true</val>
    <val>false</val>
  </param>
  <param name="lmaxvr">
    <val>14</val>
  </param>
</setup>

and expands all permutations into parametersets for further use in input templates

in that case this looks like

Dependent Parameters

If You have dependent parameters, meaning parameters that should change together with another this template supports following syntax:

<?xml version="1.0" encoding="UTF-8"?>
<setup>
<param name="gmaxvr">
<val>7 </val>
<val>8 <dep name="rgkmax" val="10"/></val>
<val>9 <dep name="rgkmax" val="11"/></val>
</param>
<param name="swidth">
<val>0.001</val>
<val>0.002</val>
</param>
<param name="spinpol">
<val>true</val>
<val>false</val>
</param>
<param name="lmaxvr">
<val>14</val>
</param>
</setup>

You can add any number of <dep> values inside the val element. This values are simply written into the <set> element together with the attribute for the <val> element.

For large series of values one can use something like the series expansion template.
