If you already have Matlab installed, type 'demo' in Matlab command window. Select 'Matlab' at the left column and you'll see three videos available for jump start. After that, type 'doc' and then find 'Matlab','Getting Started'. I taught myself Matlab this way.
Most engineering professors should be able to help in assisting you master matlab, that is how I got significantly better using the program. Just associate yourself with people who already have good skills with the program and you should be able to master it with practice!!
