Hello friends,
I checked Matlab R14 yesterday and I am little bit disappointed.
I played with it only a day but managed to create some opinion already.
1. It is strange but new matlab can not recognize the hardware OpenGL of
my video card. I had no problem with R13 Sp1
2. The Matlab IDE seems little bit prettier then in R13 but it is much slower especially the array browser on my PC (not so slow 1.8 GHz Alton with 512 Mb Ram) . In my opinion all of the IDE new features as not crytically needed are close to be redundant.
(At least in my opinion)
3. It is good that matlab functions supports integer arithmetic in R14. But it is not true that all of the function accepts int8. It seems that only the basic arithmetic operation accepts integer data type. ‘log’ for example doesn’t. In addition instead bigger speed the int types are calculated about 30% sloer then double. It means that Mathworks has not implement this feature in the matlab root but at some intermediate software level …
4. It is good that finaly they have introduced conditional break point in the meditor.
5. About matlab compiler. They have discontinue the Math C/C++ and Graphic Library.
All mlfxxxx function can not be used anymore.
The current compiler transfers the M code to C interface routines to the set of dlls and
Static libraries which contains the matlab engine. As a result as it is clearly written
In the manual of the compiler there is no sense to compile your M code to speed up its
execution.
6 GUI written on the R13 looks very different on R14 colors size of buttons on the tool bar. I have to rewrite most of my Matlab GUI.
7 Expansion of the ‘function handle’ as data type is ok. I am not sure however that the ‘nested functions’ was 100% necessary in this respect, but have not thought about it yet.
8.Lot of affords put on the Help system. That’s Ok.
9. Several warnings … I remember one about mismatch of the case of the file name and name of the function in it. For me this is annoying and also it is better I think that it is nt so big ++ to be made
10. it seems that java influence become bigger and bigger and speed slower and slower.
11 Invocation of the generic Dll is complete now. All kind of pointers are supported I hope it works stable.
12. It is good that there is some development in the RTW area … unfortunately I have not use it and I am not sure that it can be good alternative of C/C++ implementation
Can someone share its opinion and say something for the R14.
Best Regards
dora

boudaries TO END UP being a user of something not PROMISING .. JAVA the language only makes sense when running NATIVELY .. The day that the next GENERATION of INTEL's X86s will be able to RUN BYTECODE as extended INSTRUCTIONS .. Then we can talk ..
