一般情況下,我們都是在MATLAB命令行或DOS命令行下編譯MEX程序。 所用的命令就是:mex filename.c 這有很多不方便的地方:
a. 雖然mex也可以編譯C++的mex程序,但是它的主框架仍是C的 a. 當程序有多個模塊時,需要多次使用mex命令,操作很麻煩
b. 不能利用VC特有的ClassWizard自動創建和維護類
c. 不能用MFC類庫編寫應用程序
d. 不能方便地進行類似VC的項目管理
本文詳細解說如何在IDE中編譯MEX程序
We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.
The XML Toolbox converts MATLAB data types (such as double, char, struct, complex, sparse, logical) of any level of nesting to XML format and vice versa.
For example,
>> project.name = MyProject
>> project.id = 1234
>> project.param.a = 3.1415
>> project.param.b = 42
becomes with str=xml_format(project, off )
"<project>
<name>MyProject</name>
<id>1234</id>
<param>
<a>3.1415</a>
<b>42</b>
</param>
</project>"
On the other hand, if an XML string XStr is given, this can be converted easily to a MATLAB data type or structure V with the command V=xml_parse(XStr).
