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.
