How do I perform row arithmetic in OpenCVSharp?

Question

In c++ I can perform row arithmetic on a matrix:

Mat pPrime = Mat::ones(Size(3, 3), CV_64F); 
pPrime.row(0) = pPrime.row(0) / pPrime.row(2);

Is it possible to perform row arithmetic with OpenCVSharp? Trying to duplicate the c++ code results in the error The left-hand side of an assignment must be a variable, property or indexer

Mat pPrime = Mat.Ones(new Size(3, 3), MatType.CV_64F).ToMat();
pPrime.Row(0) = pPrime.Row(0) / pPrime.Row(1);

I know this is old, but I was looking for the answer to this and found the answer in the opencvsharp repo here

Your example would translate to this:

Mat pPrime = Mat.Ones(new Size(3, 3), MatType.CV_64F).ToMat();
using var pPrimeRow0 = pPrime.Row(0);
using var pPrimeRowDevided = pPrime.Row(0) / pPrime.Row(1);
pPrimeRowDevided.CopyTo(pPrimeRow0);
