The array price given below contains the price in dollars of a certain stock over 10 days

The array price given below contains the price in dollars of a certain stock over 10 days. Use MATLAB to determine how many days the price was above $20.

price = [19, 18, 22, 21, 25, 19, 17, 21, 27, 29]

Expert Solution

We have been provided with an array that contains the prices for 10 days. We need to determine for how many days the array prices were above $20.

We can create a Boolean array which will contain 1 if the array price is greater than $20; otherwise it will contain 0. We can use the sum function to calculate the number.

The MATLAB code is given below:

Input:

x = [19,18,22,21,25,19,17,21,27,29];

array = x>20;

sum(array)

Output:

We find that on 6 days the price was greater than $20.
