THE PROBLEM I NEED ANSWERED:

6) Other New Functions in Matlab Function abs: Used to compute the magnitude of a complex number Usage: Suppose we want to compute the magnitude of a variable X o X-abs = abs(X) Function find: In the last lab, we used this function to find the maximum of a vector. In this lab, we will use the function find to locate indices of a vector where the values of a vector cross a certain threshold. Consider the following row vector X: X=[1 3 4 2 1 3] o Suppose we want indices in X where X>2 o Then, we would use the find function as such: index-X = find(X > 2) In this example, index-x-12 3 6, which are the indices in X where X > 2 .Function min: Used to find the minimum value and corresponding index location in a vector Usage: Find minimum and location of minimum in vector x o [min-x, index-min-x) = min(x)
