I have a complex number

z=1-i

I want to find the argument of this complex number

2. Relevant equations

The angle it makes with the positive real axis is arctan(1/1)=pi/4

3. The attempt at a solution

This point lies in the fourth quadrant of the argand diagram.

Arg(z)= angle the z makes anticlockwise with the positive real axis = 2*pi - pi/4

is 2*pi-pi/4 the correct answer?

In matlab, the argument of this number is -pi/4 so I don't understand, doesn't the argument have to always be measured anticlockwise from the positive real axis?

Thank you in advance
