[kepler-users] Where to go with the problems of internationalization or how create account into forum?

[Edward A. Lee]

As I recall, the main reason for forcing the locale to be US
is because commas have a different meaning elsewhere.
How to parse:

   [1,2]

In Europe, this is a double matrix with one element with value 1,2
(1.2 in the US).

In this US, this is 1x2 integer matrix with two elements, 1 and 2.

I don't know of any way to reconcile this ambiguity (how does
MATLAB deal with it?  This is MATLAB syntax, which we chose
deliberately).
