If X is a vector, then find returns a vector with the same orientation as X. If X is a multidimensional array, then find returns a column vector of the linear indices of the result. exampleDescription. ~A returns a logical array or a table of logical values of the same size as A. The output contains logical 1 ( true) values where A is zero and logical 0 ( false) values where A is nonzero. not (A) is an alternate way to execute ~A, but is rarely used. It enables operator overloading for classes. In this example, you can use the find function to locate all of the elements in A less than 9. I = find (A < 9) I = 8×1 3 6 7 11 14 16 17 22 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 practice A (I) returns the same result as A (B).Elements Equal to Specific Values.
