I have an output array a[0.5,0.7,0.9], a threshold array b[0.3, 0.8, 0.7], and a lookup values array c[0,1,2] I want a finalOutput array, f, which contains the corresponding values c if a>b else -1. I decided to use a logical indexing array using the following code for thi...

Returns logical 1 (true) if the rows of two-dimensional matrix A is in sorted order, and logical 0 (false) otherwise. Matrix A is considered to be sorted if A and the output of sortrows(A) are equal. 7 setdiff(A,B) Sets difference of two arrays; returns the values in A that are...
Now the expressionA(A > 12) extracts the matrix elements corresponding to the nonzero values of the logical array. The output is always in the form of a column vector. A(A > 12) ans = 16 14 15 13 Many MATLAB functions that start withisreturn logical arrays and are very useful for...
