User allocation for Mat class #464

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Hi, thanks for javacv.
I have one question: how can I initiate 3x3 Mat class by inserting my own float 
numbers?
I found a way in C++ but I don't understand C++...
Mat M = (Mat_<double>(3,3) << 1, 0, 0, 0, 1, 0, 0, 0, 1);

 also in JavaCV, there is a Mat class method, put (row, column, float[])
but it's always giving UnsupportedOperationException.

It's great if you could share the way to assign user defined values.
Thanks,

Hiro

We can do that just as shown in the README.txt file:
    CvMat M = CvMat.create(3, 3).put(1, 0, 0, 0, 1, 0, 0, 0, 1);

And please ask your questions on the mailing list next time if possible, thank 
you.
