30 10 40 10 50
90 20 60 50 40

30 10 40
90 20 60
30 10 40

and matrix q is 

10 40 10
20 60 50

As @cxyzs pointed out in the comments, there is a log function directly implemented in OpenCV. You can find it here in the documentation.

Here is a small example of how to use it:

cv::Mat p, q;  // Your original matrices

cv::Mat logP, logQ;
cv::log(p, logP);
cv::log(q, logQ);

// Now logP and logQ contain the logarithms of the values in p and q
