help的Content里每个工具箱都有Function Reference的,该类函数都在里面典型的是点上面菜单的help->Product help->MATLAB->Function Reference点进去以后标题右边有Alphabetical List,单击可以按字母查找还有种方法可以按文件夹查找help->Function Browser全部贴出来不可能,因为实在太多了,这里贴下R2009a主要函数的a-c部分abs Absolute value and complex magnitudeaccumarray Construct array with accumulationacos Inverse cosine; result in radiansacosd Inverse cosine; result in
