I've recently downloaded a toolbox that has a variety of functions which are divided into .m files and .p files.

A demo function was available to introduce the user on the different functions as well as understanding the output. However once I run it, I receive this failure message in the Matlab console.

The P-code file C:\Users\..\xml_toolbox\xml_format.p was generated prior to MATLAB version 7.5 (R2007b) and is no longer
supported.  Use pcode to regenerate the file using MATLAB R2007b or later.

And if I open any of the available .m files, they only show these as source code:

%XML_FORMAT  Convert a Matlab variable or struct into an XML string.
%
% SYNTAX:       xmlstr = xml_format(v, [attswitch], [name] )
%
% INPUT
%   v           Matlab variable type "struct", "char", "double"(numeric),
%               "complex", "sparse", "cell", or "logical"(boolean)
%   attswitch   optional, default='on':
%               'on' writes header attributes idx,size,type for
%                    identification by Matlab when parsing in XML later
%               'off' writes "plain" XML without header attributes
%   name        optional, give root element a specific name, eg. 'project'
%
% OUTPUT
%   xmlstr      string, containing XML description of variable V
%
% SEE ALSO
%   xml_help, xml_formatany, xml_parse, xml_load, xml_save, (xmlread, xmlwrite)
