Which is faster: using false or using logical (0) to preallocate a matrix to all logical zeros? Write a script to test this. Which is faster: using a switch statement or usinga nested if-else? Write a script to test this. 36. Write a script beautyofmath that produces the following output. The script should iterate from 1 to9 to produce the expressions on the left, perform the specified operation to get the results shown on the right and print exactly in the format shown here s> beauryomath 1x8-1-9 12x8+298 123x8+3 987 1234 x8+49876 12345-59876s 7x8+7-9876543 12345678x8 8 +9 987854321 7. The Wind Chill Factor (WCF) measures how cold it feels with a given air temperature T (in degrees Fahrenheit) and wind speed V (in miles per hour). One formula for WCF is WCF-35.7 0.6T-35.7 (e 043T( Write a function to receive the temperature and wind speed as input arguments, and return the WCF. Using loops, print a table showing wind chill factors for temperatures ranging from-20 to 55 in steps of 5 and wind speeds ranging from 0 to 55 in steps of 5. Call the function to calculate each wind chill factor 38. Instead of printing the WCFs in the previous problem, create a matrix of WCFs and write them to a file. Use the programming method, using nested loops. 39. Write a script that will prompt the user for N integers, and then write the positive numbers(0) to an ASCII file called pos.dat and the negative numbers to an ASCII file called neg.dat. Error-check to make sure that the user enters N integers
