I can easily tell you what I don't like:

• No internal 64 Bit compiler.
• No real progress in the GPU support.
• No optimization of the graphics stack (Open GL performance should be improved).

[Walter Roberson]

Royi, what to you would constitute "real progress" in the GPU support? I glanced at the GPU improvements and they look to be fairly substantive to me under the assumption that it is not possible to create and test Everything You Ever Wanted To Do With A GPU in less than 6 months.

[Walter Roberson]

Royi, are you expecting Mathworks to get in to the business of writing decent Windows compilers?

Here is the official word on the Windows 64 bit version of LCC, the compiler that was provided for Windows 32 bit: http://www.q-software-solutions.de/products/lcc-win64/index.shtml

=== begin quote ===

However there are a few trouble-spots:

A fully new implemented C runtime library. Currently our wide char support is near non-existant. And it's not thread safe.

Ports of diverse libraries still to be done

No building of shared libraries

No structures exception handlign

Not all the examples have been ported

Especially the C runtime library is a hard problem. As you might know Microsoft does not provide a modern C runtime library any longer. You should use their .NET implementation.

Of course they provide a runtime library with their development environment, but to our best knowlege they do not permit to distribute it. But we have worked on facilities to enable it's use it. There's a flag you can set which will not use our library but Microsofts. You will probably have need for this to get access to a multithreading safe C runtime library.

AFAWK there is not 64-bit runtime library for any of the free compilers available. And you can check yourself, Microsoft has deprecated ! all C library functions in their new VC2005 development environment. You'll find hints to the Win32 API in there current Platform SDK, of course they can not drop that for the forseeable future. But they can underdocument this stuff, so you'll be left ot a trial-and-error approach to find out how things might (or might not work). But the base line is: Microsoft wants you to drop C completely.

Are you expecting Mathworks to be able to overcome those issues itself?

[Royi Avital]

Hello Walter,

Well, I'd expect the integration of the GPU will be more natuve. Maybe I'm wishing for too much but it looks to me that R2011a is really slim regarding new features.

About the compiler, Well, I expect nothing.

I just know the 32bit includes a built in compiler.

It's only native to expect the 64bit version to include it as well.

How and What, well I'd leave that for Mathworks, that's why they are well paid.

[Walter Roberson]

I'm not sure whether you are saying "more natural" or "more native" ? Neither phrasing is an actionable technical specification. What do you need to be able to do with GPU that you cannot do with the 2011a version?

[Walter Roberson]

Mathworks is comfortably successful, but I don't think it has the resources to convince Microsoft to give life back to its C compilers and run-times. The only realistic option, then, would be to find a company that does a good job on a thread-safe runtime and arrange with them to be able to distribute the compiler. That is going to cost money. As best I understand, downloading the Microsoft 64 bit SDK is free, but has to be done on an individual basis. How much of a price increase are you willing to live with so that you don't have to download a free software package?

If you could show me how to enable MATLAB and Photoshop integration (Which works smoothly in the 32bit version) using the external compilers I'll be able to answer you.
