Logical (Boolean) Operations
True or false conditions
MATLAB® represents Boolean data using the logical
data type. This data type represents true
and false
states using the numbers 1
and 0
, respectively. Certain MATLAB functions and operators return logical values to indicate fulfillment of a condition. You can use those logical values to index into an array or execute conditional code. For more information, see how to Find Array Elements That Meet a Condition.

Themen
- Find Array Elements That Meet a Condition
This example shows how to filter the elements of an array by applying conditions to the array.
- Reduce Logical Arrays to Single Value
This example shows how to use the
any
andall
functions to reduce an entire array to a single logical value. - Operator Precedence
Precedence rules determine the order in which MATLAB evaluates an expression.
