Can anybody help me to calculate a double integral from negative infinity to 0?

In particular, explicitly specify the "method" parameter as a function handle that calls upon quadgk() (with the function handle adjusting the calling sequence if necessary.)
If you are using R2012a you might have additional options.

I agree with you, but as i understand quadgk() calculates only one integral, and i need double intergral, what about this?
