      <itunes:summary>&lt;p&gt;Alec's suggestion is the preffered method.&amp;nbsp; But, your statement about linsolve in Maple 14 not working is not accurate.&amp;nbsp; The example below is done with Maple 15.&amp;nbsp; It works in v14 as well.&lt;/p&gt;
&lt;p&gt;From the help pages:&lt;/p&gt;
&lt;p&gt;Important: The linalg package has been deprecated. Use the superseding packages, LinearAlgebra and VectorCalculus, instead.&lt;br&gt;- For information on migrating linalg code to the new packages, see examples/LinearAlgebraMigration.&lt;/p&gt;
