MATLAB: Can I access and interact with files on the Amazon S3 cloud storage system from MATLAB 7.13 (R2011b)

amazoncloudfileMATLABs3servicesimplestorage

I have some files on the Amazon S3 cloud storage system, and I would like to access and interact with them from MATLAB like a normal file system on the computer. Is this available?

MATLAB: How to use the MATLAB Parallel Server products with the LSF scheduler in a nonshared file system

The LSF configurations with Parallel Computing Toolbox are only supported for use when:

- The MATLAB client operating system is the same type as the cluster (Windows to Windows, or Unix to Unix)

- The DataLocation set in the configuration is accessible by all computers from the same path (shared file system)

If the configuration does not meet these requirements, the LSF configurations in PCT will not work.

This limitation can be resolved by using the generic scheduler interface. The instructions and some sample scripts for integration with 3rd party schedulers can be found under the $MATLABROOT/toolbox/distcomp/examples/integration/lsf/nonshared directory.

Depending on your network and cluster configuration, you might need to modify these files before they will work in your setting. These configurations require that you have passwordless SSH/RSH and SCP/FTP setup on your client to the head node in the cluster. If you need assistance to setup passwordless remote access, ask your system administrator for help.

MATLAB Distributed Computing Server was renamed to MATLAB Parallel Server
mdce_def was renamed to mjs_def
mdce binary was renamed to mjs

MATLAB: How to create slides in MS Powerpoint 2007 using MATLAB 7.13 (R2011b)

The Microsoft APIs for Office 2007 are different from those used for Office 2003. You can create a new presentation in Powerpoint 2007 and add slides to it using MATLAB with the following code (note the commented sections for modifying an existing presentation):

% Create an ActiveX object
ppt = actxserver('powerpoint.application');
ppt.Visible = 1;
% Open an existing presentation by supplying the fullpath to the file
%ppt.Presentations.Open('C:\MyFolder\test.ppt');
% Create a new presentation
ppt.Presentations.Add()
% Add a blank slide to the presentation
layout = ppt.ActivePresentation.SlideMaster.CustomLayouts.Item(1);
ppt.ActivePresentation.Slides.AddSlide(1, layout);
% Add a custom slide and add an image to that slide
layout = ppt.ActiveWindow.Selection.SlideRange(1).CustomLayout;
slides = ppt.ActivePresentation.Slides;
newSlide = slides.AddSlide(1,layout);
%Add the image using the fullpath of the image file
pic = ...
ppt.ActiveWindow.Selection.SlideRange(1).Shapes.AddPicture( ...
fullfile(matlabroot,'toolbox','images','imdemos','football.jpg'), ...
'msoFalse','msoTrue',100,20,500,500); 
% To add another image 
pic2 = ... 
ppt.ActiveWindow.Selection.SlideRange(1).Shapes.AddPicture( ... 
fullfile(matlabroot,'toolbox','images','imdemos','football.jpg'), ... 
'msoFalse','msoTrue',200,220,500,500); 
% If you opened an already existing presentation, save it using
%ppt.ActivePresentation.Save;
% Else save a newly created presentation at a particular location
ppt.ActivePresentation.SaveAs(fullfile(pwd,'test.ppt'));
% Close Powerpoint and delete the object
ppt.ActivePresentation.Close;
ppt.Quit;
ppt.delete;
