I don't seem to be able to find any info on this but please point me in the right direction if I am mistaken:

I have a matrix (which is being fed by QT video) and I am trying to stretch the image in one direction (i.e. the y dimension) but logarithmically rather than linearly.

I have seen that jit.repos accepts jit.expr and there are examples of other expressions which effect both axes and cause strange transformations but I don't seem to be able to implement a simple logarithmic stretch along one axis.
