10==20

-> 0 % if it is false, it returns 0.

10<20

-> 1 % if it is true, it returns 1.

x=(16*64>1000)+9

-> 10 % x=1+9.

y=16*64>1000+9

-> 1 % arithmetic operators has higher precedence than relational&logical operators. 16*64>1000+9 is true, i.e. 1.

10==20 && 10<20

-> 0 % false && true

10==20 || 10<20

-> 1 % false || true

1 && 2

-> 1 % nonzero && nonzero

0 &&1

-> 0 % zero && nonzero

0 || 0

-> 0 % nonzero || nonzero

~ (1 && 2) || (0 || 0)

-> 0 % ~ 1 || 0 -> 0 || 0 -> 0

logical operators for matrix:

~[1 pi 0 3]

-> [0 0 1 0]

[1 2 pi 0 3] & [pi 4 0 9 8] % single &

-> [1 1 0 0 1]

[1 2 pi 0 3] | [pi 4 0 0 8] % single |

-> [1 1 1 0 1]

2 & [1 2; 0 3] % single &

-> [1 1; 0 1]

2 | [1 2; 0 3] % single |

-> [1 1; 1 1]
