title: Matrix operations in openCV
body: <p>I'm using OpenCV in C as a image processing tool in my latest project for performance reasons . While using Open CV , I found out that  Open CV has less library support for matrix operations . For example if wanted to add a column vector to every column in a matrix , I will have to write a custom function to do this . There are many more operations that seemed trivial in Matlab, missing in Open CV - like norm of each column , column wise min/max etc .In short all Column wise operations on a matrix seems to be missing in Open CV (I would be surprised if I didn't find more).The matrix manipulation support for library is very minimal. Is this a design decision for the library or is there some sort of an extension that can help me through this . I believe there must have been others who observed and did something about the lack of support.Any pointers ?</p>
