Output argument "dl1" (and maybe others) not assigned during call to "decsg".

Hi, What is this error ? I get it when I use PDE tool box. Thank you.

Answer 1

There is a bug in the code. If all regions evaluate to false, then the code assigns [] to three of the five outputs and returns, leaving the other two outputs undefined.

I will create a report about this.... created.

Thank you very much!

Actually I found out that if you reduce “fuzz” in the “decsg” from 10000 to a lower value this error will be resolved. For my case I used 100.

[jiye zhou]

what do you mean the 'fuzz', is it a variable or not？ cause when I open the decsg function i couldn't find 'fuzz'

States that the function "decsg" has output argument "dl1" .But while executing the function no value is passed to the output variable

[Kaveh Gharibi]

Yes. I know that. But I don't know why nothing is aasigned to dl1.
