Is it possible to generate a flow diagram from Mat

问题:

I have inherited a MatLab project with a bunch of MatLab files I need to refactor. It'd help me a lot to be able to generate a flow diagram or similar. I've Googled it and found other people asking the same question years ago, but nothing recent that works. This is the most recent thread about it:

• http://www.mathworks.com/matlabcentral/answers/28195-automatic-tool-to-generate-sequence-and-class-diagrams-uml

I've seen there is some documentation about a tool to generate class diagrams from MatLab code, but unfortunately the code I have is not OO.

Any ideas would be really appreciated :-)
