I have seen posts on citing documents, but none of them have specified IEEE format in particular. So here is my question. How do I cite technical reference manuals and software user guides in the IEEE format for references?
The IEEE Style guide gives the following format for citing reports:
The general form for citing technical reports is to place the name and location of the company or institution after the author and title and to give the report number and date at the end of the reference. Basic Format:
 J. K. Author, “Title of report,” Abbrev. Name of Co., City of Co., Abbrev. State, Country, Rep. xxx, year
 Name of Manual/Handbook, x ed., Abbrev. Name of Co., City of Co., Abbrev. State, year, pp. xx-xx.
And online sources:
 J. K. Author. (year, month day). Title (edition) [Type of medium]. Available: http://www.(URL)
 J. Jones. (1991, May 10). Networks (2nd ed.) [Online]. Available: http://www.atm.com
Examples for manuals/software:
 L. Breimann. (2003). Manual on Setting Up, Using, and Understanding Random Forests v4.0. [Online]. Available: http://oz.berkeley.edu/users/breiman/Using_random_forests_v4.0.pdf, Accessed on: Apr. 16, 2014.

Side note: this answer comments that in BibLatex you can use
@software to generate the correctly formed citation. I'm not sure however if this is supported by the IEEE style templates.
