bool's rule in matlab

In MATLAB, Boolean expressions can be constructed using logical operators such as AND, OR, and NOT that operate on logical arrays.

Here is an example of implementing Boolean logic using if-else statements:

main.m
a = true;
b = false;
c = true;

if a && b || c
    disp('One or more conditions are true')
else
    disp('All conditions are false')
end
137 chars
10 lines

The output of the above code will be "One or more conditions are true" because the condition a && b || c is evaluated as (a && b) || c which is equivalent to false || true which returns true.

Here are some commonly used Boolean operators in MATLAB:

  • & (AND) - returns logical 1 (true) only if both operands are logical 1
  • | (OR) - returns logical 1 (true) if either operand is logical 1
  • ~ (NOT) - returns true if the operand is false, and false if the operand is true
  • && (short-circuit AND) - evaluates the second operand only if the first operand is true
  • || (short-circuit OR) - evaluates the second operand only if the first operand is false

Using these operators, complicated Boolean expressions can be constructed in MATLAB.
