Relational Operators < > <= >= == ~=

Relational operations

Syntax

• A < B
  A > B
  A <= B
  A >= B
  A == B
  A ~= B
  

Description

The relational operators are <, >, <=, >=, ==, and ~=. Relational operators perform element-by-element comparisons between two arrays. They return a logical array of the same size, with elements set to true (1) where the relation is true, and elements set to false (0) where it is not.

The operators <, >, <=, and >= use only the real part of their operands for the comparison. The operators == and ~= test real and imaginary parts.

To test if two strings are equivalent, use strcmp, which allows vectors of dissimilar length to be compared.

Examples

If one of the operands is a scalar and the other a matrix, the scalar expands to the size of the matrix. For example, the two pairs of statements:

• X = 5; X >= [1 2 3; 4 5 6; 7 8 10]
  X = 5*ones(3,3); X >= [1 2 3; 4 5 6; 7 8 10]
  

produce the same result:

• ans =
  
      1    1    1
      1    1    0
      0    0    0
