Incorrect Boltzmann constant in MATLAB?
显示 更早的评论
AFAIK, the Boltzmann constant is incorrect in MATLAB.
Let's check it out:
k = physconst('Boltzmann');
and let's look at this variable k in our Workspace:
1.380650400000000e-23
1.38064852(79)e10−23
Is it going to be somehow fixed in future releases?

Physical constants "change" from year to year ...

Like Torsten said, those constants change over time due to new measurements. I would second Jan's proposal below to send in an enhancement request.

There are many sources for the value 1.3806504 also: Wiki: Knudsen number, constants.h file of the StepCore library, several books, e.g. The Feynman Lectures on Physics. I assume the value from http://physics.nist.gov/cgi-bin/cuu/Value?k (this is the source of the value posted in WikiPedia) is newer and more accurate. Please send an enhancement report to Mathworks.

I'd start at https://www.mathworks.com/support/contact_us/, go through "Create Service Request" and then the category "suggestions" seems to be fine. I'm not sure if this is teh best way, but TMW is very smart and they forward messages to the right person internally.
