must

方法一：出现如上错误之后，我们在主窗口中输入size(a)和size(b)，然后会看到参加运算的两个矩阵的维数这样会直观的看到错误的所在，逐步纠正便可。方法二：错误出现之后，可以直接查看workspace中参与运算的矩阵的维数，可以直观看到错误所在：对于其他情况，包括???errorusing==>minusmatrixdimensionsmustagree.???errorusing==>plusmatrixdimensionsmustagree.等情况，同样用以上方法检查错误，便可以解决。

这下运行没出错了，谢谢帮我解答，麻烦你了哈，^_^

为什么在matlab执行命令中出现 Matrix dimensions must agree，这句错误警告？首先，我们一应弄清这句话的意思，它的意思是矩阵尺寸必须一致，即A(m,n)和B(m,n)的行数和列数要相同。 其二，我们对照这个意思，来分析每句代码书写是否合理。我们发现Y=0.5*((pi/(x.*(r^3)))^(1/2))*(K^2/(V^2*K1^2))*exp(2*x.*r^3/(3*b0^2));题主在这个代码，没有完整使用点运算符，而是使用了一部分。其三，由于x=【1:1:10】是数组变量，所以x在Y表达式中参与运算，必须使用点运算符（如点乘.*、点除./、点乘方.^）。因此完整的代码应该为Y=0.5*((pi./(x.*(r^3))).^(1/2))*(K^2./(V^2*K1^2)).*exp(2*x.*r^3/(3*b0^2));修改后的代码，即可正常运行出图了。

1、如果是exe类型的，直接右击以管理员身份运行。2、如果是msi类型的，以管理员身份运行cmd，cd到msi文件所在的目录，执行msiexec /i "文件名" 既可以完成安装。

if you may 如果你可以if you must如果你必须

can(could)， may(might) ，must， ought以这样来区分表示可能性，can>could, may>might表示请求和允许， could>can, might>may表示委婉，might>may>could>canmust是必须，一定，用must提问，肯定回答用must，否定回答用can"tought 应该，应当。用ought to语气更严峻一些,多指按道义、法律、身体情况应当如何,具有一定的针对性; 与should区分

Individuals must be responsible for themselves. 句意：每个个体必须要为他们自己负责. individual单数是表示个人,加了s是复数形式,表示有多个不同的个体,而不仅仅是一个个体.

按ctrl+shift+esc，打开任务管理器后点击文件-运行新任务，输入explorer.exe就可以了

这个错误的意思是II和&&运算符只能连接两个逻辑标量出现这个错误的原因是||或&&运算符前后出现矢量从你的代码来看，m，n是通过find函数得到的如果有多个符合条件的数，find返回的结果就不止一个m或者n就有可能是矢量，那么m==1和n==1就是矢量，所以报以上错误粗略看你的代码，不太清楚你需要完成什么功能，不知道怎么给你改

一、too many的是many，用法与many相同，用来修饰复数可数名词。例如： He"s got too many questions to ask you．他有很多问题要问你。 二、too much的是much，用法与much相同，用来修饰。例如： We both have too much work todo．我们俩都有很多工作要做。 另外，too much还可作，用作宾语；也可作副词性短语，在句中用作状语，修饰动词。例如： You"ve given me too much．你给我的太多了。 He talked too much at the meet- ing，didn"t he？他在会上讲得太多了，是吗？ Don"t eat too much．不要吃得太多。 三、much too的是too，用法与too相同，用来修饰原级形容词或副词。例如： You"re walking much too fast． Slow down．你走得太快了，慢点。 I"m afraid that this cap is much too big for me．这顶帽子我戴恐怕太大了。 too many 后面接可数名词，too much 后面接，much too 后面接形容 must 表示客观情况必须have to 表示不得不too much +名词much too +形容词seem可用作连系动词或不及物动词，意为“似乎；好像”，其常见用法现归纳如下：　　一、“主语+ seem +（to be ）+表语”，表语多为名词或形容词，有时是其他的词或短语，以说明主语的特征或状态。例如：　　Tom seems （to be ） a very clever boy. 汤姆看上去是一个非常聪明的男孩。　　The man over there seems to be a new teacher. 那边的那个人看上去像一个新老师。　　Mr Black seemed to be quite happy. 布莱克先生好像十分快乐。　　This small town seems changed a little. 这个小城镇似乎有点儿变化。　　二、“主语+ seem + 不定式”，此句型中的seem与不定式一起构成复合谓语。例如：　　Mrs Green doesn"t seem （或seems not ） to like the idea. 格林夫人似乎不太喜欢这个主意。　　The children seemed to be eating something in the room. 孩子们好像正在房间里吃东西呢。　　The young man seemed to have changed much. 这个年轻人看起来变化很大。　　三、“It seems + that从句”，其中it 是形式主语，that引导主语从句。例如：　　It seems that no one knows what has happened in the park. 似乎没有人知道在公园里发生了什么事。　　It seems to me that Mr Brown will not come again. 在我看来布朗先生不会再来了。　　四、“There + seem to be +名词”，其中to be 可省略。seem 的单复数形式要根据后面作主语的名词的单复数形式而定。例如：　　There doesn"t seem to be much hope of our beating that team. 看来我们战胜那个队没有多大希望。　　There seems no need to wait longer. 看来没有再等的必要了。

这些琴的琴体统称offset contour body，但不相同Jaguar和Jazz Master的琴体是一样的，由经典的Stratocaster演变而来，主要区别在拾音器电路，Jaguar是在Jazz Master基础上改进的，多了一套电路。两个琴琴体上方的电路功能基本一致，一个两档拨动开关切换lead tone circuit（琴体上我们常见的那两个音量和音色旋钮，还有三档切换开关）和rhythm tone circuit（和拨档开关一起的两个黑色滑动调节旋钮，此时只有琴颈拾音器可用，三档开关无效），相当于琴上有两组音色和音量的设置。Jaguar把Jazz Master上的三档切换换成了一组三个拨档开关，一个控制琴颈拾音器，一个控制琴桥拾音器，还有一个开关。另外，Jazz Master是两个类似P90的大号单线圈拾音器，而Jaguar是改进的类似Stratocaster的单线圈拾音器，不过输出功率更大，另外拾音器有一圈金属框，能抑制一部分噪音。Mustang的琴体是另一个套路了，更另类一些，最早这琴体是Fender Duo-Sonic，然后是Mustang，后来又发展出Cyclone。这几个琴的基本都是两个单线圈拾音器的配置，Duo-Sonic第一代还是传统的音色、音量旋钮加三档切换的电路，Duo-Sonic II开始使用两个拨档开关替代了三档切换，这设计沿用到了Mustang，不过Mustang使用了类似Jaguar和Jazz Master的悬浮式琴桥（Duo-Sonic是固定琴桥，Cyclone是普通单摇琴桥），Cyclone一代使用一单一双两个拾音器，其他电路和Mustang电路一样，二代使用三单拾音器加上Jaguar的切换电路。值得一提的是Fender出过Mustang Special，使用固定琴桥，两个双拾音器，同时配置两个拨档开关和一个三档切换。Jag-Stang基本可以称为琴体更另类的Mustang，然后就是拾音器配置改成了一单一双，琴桥形状和Mustang类似。

因为那些作品都是DJ Mustard制作的（例如don"t tell em,I don fuck with you,feelin myself等等 ），这句话的原句其实是Mustard on the beat,hoe,不过是为了告诉你“没错这么屌的作品就是我做的”而已。

选A理由如下：（语法上分析）it在句中是形式主语，代指whattheproblemitselfis.。what充当连词，引导主语从句，在从句中当作宾语。（句意上分析）首先要知道这个问题本身是“什么”，才能确定能不能解决。所以选what。排除法：句子不是定语从句，C排除：句子不是强调句，排除BD与句意不符。

what 引导的是主语从句，在从句中做表语，且这个是真正主语，it为形式主语

may,might 1) 表示请求和允许.might比 may语气更委婉,而不是过去式.否定回答时可用can"t 或mustn"t,表示“不可以,禁止”. ----Might/ May I smoke in this room? ---- No,you mustn"t. ---- May/Might I take this book out of the room? ---- Yes,you can.(No,you can"t / mustn"t.) 用May I...征徇对方许可时比较正式和客气,而用Can I...在口语中更常见. 2）用于祈使句,表示祝愿. May you succeed! 3) 表示推测、可能性（不用于疑问句）. might不是过去式,它所表示的可能性比may小. 1．He may /might be very busy now. 2．Your mother may /might not know the truth. 三、 must 1) 表示必须、必要. You must come in time. 在回答引出的问句时,如果是否定的,不能用mustn"t（禁止,不准）,而用needn"t,don"t have to（不必）. ---- Must we hand in our exercise books today? ---- Yes,you must. ---- No,you don"t have to / you needn"t. 2) must是说话人的主观看法,而have to则强调客观需要.Must只有一般现在时,have to 有更多的时态形式. 1． he play isn"t interesting,I really must go now. 2． I had to work when I was your age. 3) 表示推测、可能性（只用于肯定的陈述句） 1． You"re Tom"s good friend,so you must know what he likes best. 2． Your mother must be waiting for you now.

might是may的过去式.might表示允许或请求,语气比may委婉；表示没有把握的推测；may放在句首，表示祝愿。might表示推测时，不表示时态。只是可能性比may小。总的来说应该就是这样啦.

这个我刚刚给孩子们讲过 （1）can can表示体力、脑力方面的能力或客观的可能性,也可表示对事情的推测.口语中, 在询问或说明一件事可不可以做时,常用“can”代替“may”.情态动词“can”的过去式是“could”,否定式是“cannot”通常缩写成“can"t”,“could”的否定式是“could not”,通常缩写成“couldn"t”.如：Can I help you?(要帮忙吗?)/ He can swim.(他会游泳)/ That can"t be Mr Li.(那不可能是李先生) （2）must must表示“必须”、“一定”的意思.表示“必须”时否定形式是mustn"t；表示“一定”时,否定形式是“can"t” 如：We must be very careful when we cross the road.(我们过马路时一定要非常小心)/ It must be Jack.(那准是杰克)/ I haven"t seen Kate today. She can"t be here.(我今天没有看到过凯特,她不可能在这里) 注意：用must(必须)进行提问时,肯定回答用must,否定回答用needn"t；用must(一定)进行提问时,肯定回答仍用must,但是否定回答用can"t.如：Must we clean the room before we leave? –Yes,you must.或No,you needn"t.(我们走之前必须要打扫房间吗?是的,必须打扫./ 不,不需要.) / Must she be in the romm? –Yes,she must.或No,she can"t.(她一定在房间里吗?是的,一定./ 不,不可能在.) （3）may may表示允许、请求或可能性,用may提问时,肯定回答一般用Certainly或Yes,you may.;否定回答一般用can"t或mustn"t. 如：May I ask you a question?—Certainly.(可以问你一个问题吗?当然可以)/ You may go now.(现在你可以走了)/ It may be in your pocket.(它可能在你的衣袋里) （4）might might是may的过去式,表示请求的时候语气更委婉,表示猜测的时候语气更弱

must have been和must be的区别在have。因为本句是指对过去情况的推测，所以必须要用“情态动词+动词的完成式”。have在这里表示是动作已经完成。所以must have been是对过去的事实的肯定猜测，must be是对现在事实的肯定猜测。例句：Sorry I made such a fool of myself last night. I must have been drunk.翻译：对不起，我昨晚真是出丑了，我一定是喝醉了。must的用法1、must表示义务或强制，含意是“必须”“应当”；其否定结构表示“不许可”或“不应该”；用于一般疑问句时，表示征求对方的意见，其肯定答语用Yes, please或I"m afraid so,否定答语用needn"t或don"t have to; must在间接引语中表过去。2、must表示必然性，一般只用于肯定句中，有时表示“意愿”，带有感情色彩。
