Find Array Elements That Meet a Condition This example shows how to filter the elements of an array by applying conditions to th ...

< 9. For example, A(1,1) is 13 , so B(1,1) is logical 0 (false). However, A(1,2) is 2 , so B(1,2) is logical 1 (true). Althou ...

The result is a column vector of linear indices. Each index describes the location of an element in A that is less than 9, so in ...

Finally, find the elements in A that are less than 9 and even numbered and not equal to 2. A(A<9 & ~mod(A,2) & A~=2) ...

Determine if Arrays Are Logical To determine whether an array is logical, you can test the entire array or each element individu ...

Test an Entire Array Use the islogical function to test whether A is logical. islogical(A) ans = 1 The result is logical 1 (true ...

The result is a matrix of logical values of the same size as A. arrayfun(@islogical,A) always returns a matrix of all logical 1 ...

Reduce Logical Arrays to Single Value This example shows how to use the any and all functions to reduce an entire array to a sin ...

The resulting matrices have values of logical 1 (true) where an element is even, and logical 0 (false) where an element is odd. ...
