No. It exists long ago probably from the first MATLAB

is equivalent to

touzi('capacity')

Common example are 'load', 'print' command

For example when you do

> load -ascii data.txt

is exactly like

load('-ascii','data.txt')

Yes, this has been part of MATLAB for a long time.

There are two ways to invoke most functions in MATLAB, the command form and
the functional form.

Yes. This is known as "command-function duality".

Another common example (although not always as common as I'd like, and I'm
guessing few people think of it this way) is HELP.

"help sin" is the same as "help('sin')".
