MATLAB: How to switch the value of a boolean.

Question

Hi, is there any function to do the following :

a = true;
b = someFunction(a)
    ==> b = false
b = sumeFunction(b)
    ==> b = true;

thank you.

Answer 1

b = ~a;
c = ~b;

or if you are looking for the functional form

b = not(a);
c = not(b);
