Logical (Boolean) Operations

True or false conditions

MATLAB^®represents Boolean data using thelogicaldata type. This data type representstrueandfalsestates using the numbers1and0, 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 toFind Array Elements That Meet a Condition.
