Revision history [back]

I am comfused by the following pseudocode:

cv::mat a(row,col,datatype); /* fill a */ cv::mat b(row,col,datatype);//allocate memory for b, b has same size with a

for(int i=0; i< a.rows; i++) {

b.row(i) = a.row(i);//for each line

}

does b shares the same date with a?

I am comfused by the following pseudocode:

cv::mat a(row,col,datatype); /* a(row,col,datatype);

/*

codes fill a */ data in a

*/

cv::mat b(row,col,datatype);//allocate memory for b, b has same size with a

for(int i=0; i< a.rows; i++) {

b.row(i) = a.row(i);//for each line

}

does b shares the same date with a?

I am comfused confused by the following pseudocode:

cv::Mat a(row,col,datatype);
 /*
 
/*
 
codes fill data in aa
 */
 
*/
 
cv::mat cv::Mat b(row,col,datatype);//allocate memory for b, b has same size with aa
  
for(int i=0; i< a.rows; i++)
{
 
{
b.row(i) = a.row(i);//for each line
 
}line
}

does b shares the same date with a?
