log ratio transformation and calculating correlations between pairs of log-ratio variables

I am new to matlab and have a question. I have a column vector from a matrix of data called 'tracem' and I need to use the basic log-ratio transformation procedure, using the column 'S' from matrix 'tracem' as the common denominator, to calculate correlations between pairs of log-ratio variables.

I have no idea how to do this. any help is appreciated!

You will need to write a script for it. Go to this link to learn Matlab fundamentals.

Once you are through it, it will be easy to code your algorithm just like you do in other languages.
