How to tell where an application hangs

I have a long running Matlab application that "hangs" at a certain point during the processing. However, if I try to interrupt it with CTRL-C nothing happens. The only way to stop it is to kill the Matlab process in the Windows task manager. This happens even if I run the code in the debugger (setting a breakpoint and pressing continue).

It's very hard to debug as I really don't know where to start looking in the code.

Any idea to tell where the hang occurs?

Matlab consumes CPU during the "hang" so this may be a logic error in the code sending it into an infinite loop. The code also calls some Java routines. I'm using R2018b under Windows.

hello there,

im new to matlab.

neither i know any designing or analysing tools

im a graduate in aeronautical engineering

didnt do my studies well, after 3 years of arrears. getting out with a degree

i completed my college by 2014

unemployed right now.

with a thirst of getting inside research oriented domain. i started to learn skills that might help me persuing my passionate career.

where i found out that matlab is the techno mathamatical tool that helps most of the R&D job.

and knowing it might place me in a world class exposed R& D domain.

i find that hear everything if costly.

im basically from an agricultural background from india.

im not tending to get everything for free. but till i leatn and get into a position of paying back,,,

i need your help guys.

i want to learn matlab . expecially CFD relatingly.

and FEA

so please guide me to learn things and lerring me to develope in a domain.

which is the best resource.

what should i know before starting it.

ive grasped some knowledge looking into youtube. but im unable to comprihend or conclude suddenl, as coading is completly new to me...

[Precise Simulation]

For learning CFD and FEA with Matlab you can maybe try the FEATool Multiphysics toolbox with built-in modeling and simulation tutorials.
