matlab中或和非,Matlab Java 中的“与或非”
Matlab:
Logical Operators: Short-Circuit && ||
expr1 && expr2
expr1 || expr2
1 & 256 // result is 1
1 & 255 // result is 1
expr1 && expr2 represents a logical AND operation that employs short-circuiting behavior. That is, expr2 is not evaluated if expr1 is logical 0 (false). expr1 || expr2 represents a logical OR operation that employs short-circuiting behavior. That is, expr2 is not evaluated if expr1 is logical 1 (true).
and, &
A & B
and(A,B)
1 & 256 // result is 1
1 & 255 // result is 1
A & B performs a logical AND of arrays A and B and returns an array containing elements set to either logical 1 (true) or logical 0 (false).
bitand
C = bitand(A,B)
C = bitand(A,B,assumedtype)
1 & 256 // result is 0
1 & 255 // result is 1
Java:
& && | ||都是位操作
1 & 256 // result is 0
1 & 255 // result is 1
