Loop/Array Test Practice 1 A data scientist is writing a program to sort through a data set on temperature. She has long arrays of temperature data, and corresponding arrays of the time the temperature data was collected. These arrays are of equal length. The data scientist only cares about the times that the temperature drops below freezing, and wants to create a simplified representation of that data in a new array. Put yourself in the data scientist's shoes. Write a function that takes two inputs, an array of temperatures, and an array of times. Your function should return a new array of all of the times that the temperature drops below freezing. Assume that temperature is in degrees Celsius, and that the times are stored in a numeric format (i.e., the time array is an array of numbers). For example, with the arrays: Temp = 20 148-1-410-581; Time = [1000 1100 1200 100 200 300 400 500 600]; Your function would return: Output = [100 200 500]

Explanation / Answer

Save this in file getFreezingTime.m

function output = getFreezingTime(temp, time)
output = [];
lengt = size(temp, 2);
for i = 1:lengt
if temp(i) < 0
output = [output time(i)];
end
end
end

% for testing

put this in console to match output

getFreezingTime([20 14 8 -1 -4 1 0 -5 8], [1000 1100 1200 100 200 300 400 500 600])
