voidmexFunction (intnlhs, mxArray *plhs[],intnrhs,constmxArray *prhs[] ) { } 编写Mex程序的编译器可以使用matlabdiamante编辑器,也可以使用自己的C++编译器你,如VS2008等。 上面这四个参数分别用来输出和输入数据:nlhs是输出参数个数,plhs是输出参数指针,nrhs是输入参数个数,prhs是输入参数指针。
In theSizeproperty, specify the size as the upper bound. For example, to specify a 2-by-4 matrix as the largest acceptable size, enter[2 4].If you do not know the upper bound of the size, useInfas the higher bound to create an unbounded variable-size array.(since R2023b)For more...

Array Creation To create an array with four elements in a single row, separate the elements with either a comma (,) or a space.(使用逗号或空格分离。 a = [1 2 3 4] returns a = 1 2 3 4 This type of array is arow vector. ...
With diff(X,n,dim), where n >= size(X,dim), diff returns an empty array. Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 dim— Dimension to operate along positive integer scalar Dimension to operate along, specified as a positive...
