m-file for principal axis factoring solution of factor analysis

File Information
Description	The reason to favour this method opposite to maximum likelihood (Statistics toolbox) is no distributional assumptions. In comparison to SPSS program, this provides the same results. We expect identical numerical solution, especially advantage of singular decomposition. Program includes the Heywood case solution in communalities and orthogonal varimax rotation.

15 Mar 2007	Jamie Burke	Great code. Really, it works similarly to SPSS.
17 Mar 2007	John D'Errico	Well done.
04 Feb 2008	yuejin zhang	This function is much more robust than 'factoran'. It works with rank defficient data sets and runs faster too. Nice work!
