Hello,
I use this code :
Mat sampleMat = (Mat_<float>(1,1) << (trainData[i][0]));
But I want to create mat object with a loop. Maybe it looks like this :
Mat sampleMat = (Mat_<float>(1,size) << for(j < size)(trainData[i][j]));
How can I do this?
The following steps need to be done to achieve this:
// Allocate memory for your matrix (e.g. 8x8 int matrix)
Mat temp_matrix (15, 15, CV_8UC1);
// Make a double loop over indexes and assign values
for(int rows; rows < 15; rows++){
for(int cols; cols < 15; cols++){
temp_matrix.at<uchar>(rows,cols) = selected_value;
}
}
I do know there are more effective ways to fill up matrices, but I haven't been in need since this is performing perfectly real time on my system. Maybe take a look at this page.
