Tracking multiple variables in Matlab

Guys,I have a big task and maybe you had problem like this

Implement a solution for tracking the evolution of a set of variables. The input is a matrix. Each column contains the variables (some measured values) at some location or time interval. These values represent parameters of some process that change slightly, however the data may be incomplete (in other words, there is no guarantee that consecutive columns represent continued variable at the same position). Find the connections between closest values between each column and next column. Each track links values from several consecutive columns. It does need to continue over all columns: some tracks may end, if there are no good connection, some other tracks may begin later. The output is a plot of tracks.
