Useage: [files,mri] = mri_toolbox_recent([filename],[command])
filename = path & filename of an mri_toolbox .mat file to
be added to the recent files list
command = 'load', to load one of the recent files
'clear', to clear all recent files
If filename is not given, the function returns
the most recent files saved (if any). If it
is given, the filename is added to the list.
If the load command is given, filename.mat is
loaded and the mri struct is returned. Otherwise
the mri struct is empty.
Tracks recent mri structure saves to .mat files
for the mri_toolbox gui. The return variable
'files' is a cell array of strings containing
the filesystem location of recent mri files saved.
The recent files list is limited to 20.</pre></div><!-- crossreference --><h2><a name="_cross"></a>CROSS-REFERENCE INFORMATION <a href="#_top"><img alt="^" border="0" src="../up.png"></a></h2>This function calls:<ul style="list-style-image:url(../matlabicon.gif)"></ul>This function is called by:<ul style="list-style-image:url(../matlabicon.gif)"><li><a href="mri_toolbox.html" class="code" title="function [ varargout ] = mri_toolbox(command)">mri_toolbox</a> mri_toolbox - Graphical user interface (GUI) to various MRI tools</li><li><a href="mri_toolbox_defaults.html" class="code" title="function [mri] = mri_toolbox_defaults(command,mri);">mri_toolbox_defaults</a> mri_toolbox_defaults - Create, read, write mri_toolbox defaults</li></ul><!-- crossreference --><h2><a name="_source"></a>SOURCE CODE <a href="#_top"><img alt="^" border="0" src="../up.png"></a></h2><div class="fragment"><pre>0001 <a name="_sub0" href="#_subfunctions" class="code">function [ files, varargout ] = mri_toolbox_recent(filename,command);</a>0002 0003 <span class="comment">% mri_toolbox_recent - Keep track of mri_toolbox .mat files</span>0004 <span class="comment">%</span>0005 <span class="comment">% Useage: [files,mri] = mri_toolbox_recent([filename],[command])</span>0006 <span class="comment">%</span>0007 <span class="comment">% filename = path & filename of an mri_toolbox .mat file to</span>0008 <span class="comment">% be added to the recent files list</span>0009 <span class="comment">% command = 'load', to load one of the recent files</span>0010 <span class="comment">% 'clear', to clear all recent files</span>0011 <span class="comment">%</span>0012 <span class="comment">% If filename is not given, the function returns</span>0013 <span class="comment">% the most recent files saved (if any).
