Greater-than operator: tests element by element whether A is larger than B.

Category: Language Fundamentals > Operators and Elementary Operations

Syntax

C = A > B

Description

The comparison is element-wise with implicit expansion and returns a logical array. It is typically used to build conditions, to count with sum(x > t), or to filter with x(x > t). Comparisons with NaN are always 0.

Inside if and while, an array condition is true only when all its elements are nonzero.

Input arguments

A, B

Numeric, logical or char arrays (only the real part is compared for complex values). Sizes must be compatible, or one of them a scalar.

Output arguments

C

Logical array: 1 where the relation holds, 0 elsewhere.

Example

x = [4 -1 7 0];
x > 0
sum(x > 0)
x(x > 0)

ans = 1×4 logical array

   1   0   1   0
ans = 2
ans = 1×2

     4     7
