lt (MATLAB Functions)

Test for less than

Syntax

```
A < B
lt(A, B)
```

Description

A < B compares each element of array A with the corresponding element of array B, and returns an array with elements set to logical 1 (true) where A is less than B, or set to logical 0 (false) where A is greater than or equal to B. Each input of the expression can be an array or a scalar value.

If both A and B are scalar (i.e., 1-by-1 matrices), then MATLAB returns a scalar value.

If both A and B are nonscalar arrays, then these arrays must have the same dimensions, and MATLAB returns an array of the same dimensions as A and B.

If one input is scalar and the other a nonscalar array, then the scalar input is treated as if it were an array having the same dimensions as the nonscalar input array. In other words, if input A is the number 100, and B is a 3-by-5 matrix, then A is treated as if it were a 3-by-5 matrix of elements, each set to 100. MATLAB returns an array of the same dimensions as the nonscalar input array.

lt(A, B) is called for the syntax A < B when either A or B is an object.

Examples

Create two 6-by-6 matrices, A and B, and locate those elements of A that are less than the corresponding elements of B:

A = magic(6);
B = repmat(3*magic(3), 2, 2);

A < B
ans =
     0     1     1     0     0     0
     1     0     1     0     0     0
     0     1     1     0     0     0
     1     0     0     1     0     1
     0     1     0     0     1     1
     1     0     0     0     1     0
