Matlab: How to profile inefficient lines of code with running count visualisation?

I need to find lines that are executed most. For example, Eclipse has a plugin at least for Java that shows the line counts. Does this kind of plugin or tool exist with Matlab?
P.s. I asked the same question in SO: I don't know yet which place is better for Matlab-style questions -- anyway I will close one when other solved and then redirect -- sorry about cross-posting but this is important thing in profiling.

No it's there in 2012a but just hidden away. You will be able to use the commands in the link above.

I was able to find p=profile('info');p.FunctionTable.ExecutedLines but I cannot find a way to visualise the data-dump, it is pretty hard reading.

I was able to profile the inefficient lines by clicking the blue hyperlinks in the Profile Summary. This was solved by the SO thread mentioned. Anyway thank you for your help!

You should lookup the MATLAB Profiler. This is easily accessible through the toolbar in 2012b onwards (run and time is one way).

Thanks, I got the 2012B now running but I cannot yet find a way to generate the linewise analysis. I did all small working examples there but not seeing any colours.
