Is MATLAB case-sensitive?

I would like to know if MATLAB is completely case-sensitive.

Generally speaking, MATLAB is case-sensitive.

MATLAB is case sensitive for function, script, and variable names for all platforms, but name-value pairs can sometimes be insensitive. 

For example, 

>> plot(1:10,'linewidth',3)
>> plot(1:10,'LineWidth',3)
>> plot(1:10,'LINEWIDTH',3)

works the same way, but

>> Plot(1:10) 

won't work.
