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).

中心點(diǎn)漂移是一種非監(jiān)督聚類算法（與k-means算法相似，但應(yīng)用范圍更廣些),可用于圖像分割，基于Matlab實(shí)現(xiàn)的源碼。 MedoidShift is a unsupervised clustering algorithm(similar to k-means algorithm, but can be used in border application fields), can be used for image segmentation. Included is the Matlab implementation source code.

Servomotors are available as AC or DC motors. Early servomotors were generally DC motors because the only type of control for large currents was through SCRs for many years. As transistors became capable of controlling larger currents and switching the large currents at higher frequencies, the AC servomotor became used more often. Early servomotors were specifically designed for servo amplifiers. Today a class of motors is designed for applica-tions that may use a servo amplifier or a variable-frequency controller, which means that a motor may be used in a servo system in one application, and used in a variable-frequency drive in another application. Some companies also call any closed-loop system that does not use a stepper motor a servo system, so it is possible for a simple AC induction motor that is connected to a velocity controller to be called a servomotor.

本代碼為編碼開關(guān)代碼，編碼開關(guān)也就是數(shù)字音響中的 360度旋轉(zhuǎn)的數(shù)字音量以及顯示器上用的（單鍵飛梭開 關(guān)）等類似鼠標(biāo)滾輪的手動計(jì)數(shù)輸入設(shè)備。 我使用的編碼開關(guān)為5個引腳的，其中2個引腳為按下 轉(zhuǎn)輪開關(guān)（也就相當(dāng)于鼠標(biāo)中鍵）。另外3個引腳用來 檢測旋轉(zhuǎn)方向以及旋轉(zhuǎn)步數(shù)的檢測端。引腳分別為a,b,c b接地a，c分別接到P2.0和P2.1口并分別接兩個10K上拉 電阻，并且a，c需要分別對地接一個104的電容，否則 因?yàn)榫幋a開關(guān)的觸點(diǎn)抖動會引起輕微誤動作。本程序不 使用定時(shí)器，不占用中斷，不使用延時(shí)代碼，并對每個 細(xì)分步數(shù)進(jìn)行判斷，避免一切誤動作，性能超級穩(wěn)定。 我使用的編碼器是APLS的EC11B可以參照附件的時(shí)序圖 編碼器控制流水燈最能說明問題，下面是以一段流水 燈來演示。
