Hello, I have just little question. Im used to write commands in Caps Lock all the time. Is there any chance I can allow it in Preferences window? Or in some Settings?
For example I have command rand > RAND , ans > ANS , sin > SIN , sort > SORT, who > WHO , etc etc...
I hope you get my point.

No, this will not work.
Since R2009a Matlab is case-sensitive even under Windows. You cannot call sin() using the name SIN(). But you could write a wrapper function:
function y = SIN(x)
y = sin(x);
end
But this will slow down the processing and increase the confusion level. You cannot share your code afterwards and a collaboration with others requires, that they obtain a bunch of useless functions from you.
Functions with a variable number of inputs and outputs need more code.
Avoid such clutter.
By the way, ans is not a function. It stores the last replied value of commands, which are not caught in an output. Avoid to use it in productive code, because it is too volatile. During debugging ans can be overwritten and everything, which impedes debugging is the enemy of the programmer.
