Logical (Boolean) Operations - MATLAB & Simulink (original) (raw)

True or false conditions
MATLAB® represents Boolean data using the logical data type. This data type represents true andfalse 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 Conditions.

- Find Array Elements That Meet Conditions
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 theanyandallfunctions to reduce an entire array to a single logical value. - Operator Precedence
Precedence rules determine the order in which MATLAB evaluates an expression.
