Note[1] SeDuMi 1.21 crashes on Matlab 2007b/WindowsXP 2002, so utilizes SeDuMi 1.1R3 with Matlab 2007b/WindowsXP 2002[2] Please download the appropriate version for your OS and platform. Currently, the latest release, SeDuMi 1.2 is supportred only on 64 bit Linux and Matlab using 2007b. The version before that, sedumi 1.1R3 is supported on almost all 32 bit systems. Version before that are no longer supported.--The SeDuMi Team Imre Polik--在SeDuMi主頁上下了一個1.21版本，結果裝不上，不知啥原因，忽然想到以前用的CVX中好像有SeDuMi，查看一下是1.2版本，想想CVX好用的，裡面包含的1.2應該也可以用，但是單獨安裝還是不行。終於在網上找到一段The SeDuMi Team的Imre Polik的留言，才明白32位機器要用1.1R3版本，於是下載，安裝，測試果然正確。嘻嘻。
