区别一
no matter what只能放在句首，在句中，只能用whatever，"no matter +疑问词" 或"疑问词+后缀ever" 。
No matter what happened, he would not mind. =Whatever happened, he would not mind.
不管发生什么，他不在意。
区别二
no matter 不能引导主语从句和宾语从句。
（错）Prisoners have to eat no matter what they're given.
（对）Prisoners have to eat whatever they're given.囚犯们只能给什么吃什么。
区别三
what和ever分开写,则作“到底,究竟”解,这时它和on earth,in the world相同,起强调作用.
What ever do you mean?= What do you mean on earth?
区别四
whatever 是连接性代词性和形容词，既可以引导让步状语从句，也可以引导名词性从句。同 what一样，whatever 在从句中充当主语、宾语、表语或定语。
如果 whatever引导的是让步状语从句，可以用no matter取代；如果引导的是名词从句，则不能用 no matter 取代。
区别五
what也可以引导名词性从句意为“the thing which”与“whatever”含义相同.用法完全与whatever相同的词还有whichever,whoever.

no matter what用于状语从句 whatever用于宾语,表语,主语从句,不能用同位语从句. 说明: 1.Whatever is said by our parents, we should obey. （ Whatever our parents say,-----------------------）. 2.The problem is whatever the weather will be like 。 比较No matter what(不用Whatever） the weather will be like,the competetion has to go on.（状语从句） 3.I try to understand whatever the the teachers explain to us in class. （例1、2、2分别属于主、表、宾从句） 4. The fact that he makes little progress no matter what（不用whatever） knowledge he tries to master leads to his being absent from classes (这里no matter what引导让步状语从句).(that 不能题换成whatever）。因whatever 不引导同为语从句。 5。No matter what he says ,I won't believe him. 6. (比较)Whatever he says is not believable.(主语从句) 7。You can choose whatever you likes.(宾语从句) 简单的来记就是：状语从句，两词可以互换，名词性从句时，不能换

1whatever可用作连接词或连接副词,引导让步状语从句,表示“无论,不管”的意思.此时,可用no matter what结构来替换其意完全相同.位置前后置都可以.
2whatever还可以引导名词性从句,同时起先行词和关系代词的作用.相当于anything that或all that,有任何一切这类意思.此时不能用no matter what替换.
3what和ever分开写,则作“到底,究竟”解,这时它和on earth,in the world相同,起强调作用.e.g.What ever do you mean?= What do you mean on earth?
4what也可以引导名词性从句意为“the thing which”与“whatever”含义相同.
5用法完全与whatever相同的词还有whichever,whoever.本回答被网友采纳

no matter是不论 你说的应该是no matter what还有whatever 它们还是有些区别的，就是引导的从句不同 whatever可以引导状语从句和名词性从句 而no matter what只可以引导状语从句本回答被提问者采纳
