What does && mean in Matlab?

Up vote 8. Both are logical AND operations. The && though, is a “short-circuit” operator. From the MATLAB docs: They are short-circuit operators in that they evaluate their second operand only when the result is not fully determined by the first operand.

Which is a logical operator?

A logical operator is a symbol or word used to connect two or more expressions such that the value of the compound expression produced depends only on that of the original expressions and on the meaning of the operator. Common logical operators include AND, OR, and NOT.

Actually, is “a && b”. && is the logical AND operator used for logical tests. For example: “if(a && b) { i++;}”. Any value different from 0 is considered TRUE. In this case: a && b is the same as 0 && 5 that is the same as FALSE AND TRUE.
