Problem 3 A highway manager has asked for help programming a highway

advisory sign. A digital wind gage will provide a wind gust speed to the device

which will display the appropriate restriction. In order to test the device a function

program is required which uses if statements and prints to the screen, (fprintf) the

appropriate restriction as shown below.

Wind Speed Restriction

Gusts <20 mph | 55 mph speed limit

Gusts 20<35 mph | 40 mph speed limit

Gusts 35<45 mph | 40 mph speed limit; Bridge closed to pedestrians, bicycles, and buses.

Gusts 45<50 mph | 35 mph speed limit; Bridge closed to vehicles with trailers, roof rack items and motorcycles.

Gusts 50< 65 mph | 30mph speed limit; Bridge closed to all vehicles except cars.

Gusts > 65 mph | Bridge closed to all traffic.

The first line of your function should be function [ ]= HW3_P3(windgust)

This is a MATLAB question. Please show the function you created! Thank you!

Solution

the matlab code shall be as follows:

function [ ]= HW3_P3(windgust)
if windgust<20
fprintf(\'55 mph speed limit\');
else if windgust<35
fprintf(\'40 mph speed limit\');
else if windgust<45
fprintf(\'40 mph speed limit; Bridge closed to pedestrians, bicycles, and buses\');
else if windgust <50
fprintf(\'35 mph speed limit; Bridge closed to vehicles with trailers, roof rack items and motorcycles\');
else if windgust<65
fprintf(\'30mph speed limit; Bridge closed to all vehicles except cars\');
else
fprintf(\'Bridge closed to all traffic\');
end
end
end
end
