详解OpenCV中的cvCreateMat()函数

CreateImage函数

Creates an matrix header and allocates the matrix data   //创建矩阵头并分配矩阵数据。

.C：CvMat* cvCreateMat(int
rows,int cols,int type)   //函数原型

Parameters

Rows -Numbers of rows in the matrix       //矩阵的行数

Cols   - Numbers of cols in the matrix
    //矩阵的列数

   type   - The type of the matrix elements in the form CV_<bit depth><S|U|F>C<number of channels>,where S=signed,

U=unsigned,F=float..For example ,CV_8UC1 means the elements are 8-bit unsigned and there is 1 channel,andCV_32SC2 means the elements are 32-bit signed
and there are 2 channels.

                注：这里type可以是任何预定义类型，预定义的结构如下：CV_<bit depth><S|U|F>C<number of channels>,于是，矩阵的元素可以是32位浮点型数据（CV_32FC2）,或者是8位三元组的整型数据（CV_8UC3）
