The website of Pololu or several (small) DC motor manufacturers generally only supply very few parameters such as stall torque, stall current, rated voltage etc. To get more information about the motor behaviour, these parameter values can be combined and analyzed.
This script does the same. The input is similar to the link here (https://www.pololu.com/product/2380/specs)
The output curves and methodology is similar to the link here (https://www.pololu.com/product/2380/faqs)
Re-written to include all units as per the feedback from users.

2.0.0.0

*small correction on the figure axis labels.
*Fixed the legends on the plots.
*The matlab window will now show the points of maximum efficiency and output power w.r.t current and torque.
Thanks to Pololu support (Jonathan Kosh) for these suggestions.
Corrected resistance formula which was not taking into account that current is in mA.
Added some comments to understand the units involved.
