Algunos compañeros y yo estamos debatiendo sobre el resultado de esta operación, alguno decimos que nueve, otros que es uno. 9/2(1+2). Que resultado arroja en MatLab, no lo tengo instalado en esta máquina.

It is an error in MATLAB as MATLAB has no implied multiplication.
If it is interpreted as 9 / (2 * (1+2)) then that would be 9/6; if it is interpreted as (9/2) * (1+2) that would be 27/2. Neither result would be the 9 or 1 that you mentioned.
