Question

b) The harmonic mean is another way of calculating a mean for a set of natural numbers, which is given by the equation: harmonic mean = \frac{n}{\frac{1}{x_1} + \frac{1}{x_2} + \dots + \frac{1}{x_n}} Write a function named [ind, hm] = myHarmmean(x) that accepts a vector x of arbitrary length n: x = [x_1, \dots, x_n], and returns the indices of non-positive elements of x in ind and the harmonic mean of positive elements of x. For example: 1 x = [1 -1 2.3 4 -3 6.5]; 2 [ind, hm] = myHarmmean(x) 3 ind = 4 [2 5] 5 hm = 6 2.1755 Verify your function on two examples of your choice (with different lengths n ? 5, and the vector must include negative elements), and print your results and the results returned by the built-in MATLAB function harmmean. Note: you are not allowed to call the built-in MATLAB function harmmean in myHarmmean.
