terminating ALL m-scripts

hi all,

I'm currently working on TargetLink Code generation and I am facing problem to terminate the whole process if a problem is found:

>tl_generate_code.m
   > tl_eval_hook.m
       > pre_codegen_hook.m

"*pre_codegen_hook*.m" is called by "tl_eval_hook.m", which is likewise called by "tl_generate_code.m".

The problem I'm facing now is that I don't know how to terminate the WHOLE process if i find problem in the called script "*pre_codegen_hook*.m". I tried using the command "return" but it only brings me to the caller and it doesn't terminate the whole process. Although this is actually about TargetLink but I guess this is applicable in normal MATLAB script.

use error

help error

ahh I left out another script: In "pre_codegen_hook.m" another script "extrainfo.m" is called. :S

i just tried:

error('Terminated by user!')

in "extrainfo.m" but it continued to process the rest of the contents of "pre_codegen_hook.m".

any idea?

[Robert Cumming]

is it in a try catch block?

[Qi Hao Goh]

yea. but it didn't return the "catch" result though. And I don't expect that to be the case too :)

so error doesnt work with try catch block?

[Robert Cumming]

It will go into the catch part and then continue with the calling function. If you want it to throw an error use rethrow or similar

[Qi Hao Goh]

good one. Just that I can only edit "pre_codegen_hook.m" and "extrainfo.m". The rest are default script from TargetLink. :/

any other idea?

afraid not - apart from exit! Which will ofcourse close matlab itself...
