Hi, I have two matrices of xy co-ordinates, one being the outline of a train and one being the outline of the structure the train is passing through. I would like to find the minimum distance between these matrices to work out the minimum clearance. I am new to MATLAB and any help would be appreciated, thanks in advance.

Use one matrix to generate the curve and the other dataset as a list of points for which you want to compute the distance to the curve. Finally, take min(.) of the distances computed.
After this, you could reverse the roles of curve and list of points to see whether you get the same distance.
