Question

Matlab Question:

Important! Read: No for or while loops may be used; must use the disp function

The top speeds of sportscars, given in miles per hour, are:

155 mph BMW M5

217 mph Lamborghini Aventador Spyder

205 mph Ferrari 488

205 mph Nissan GTR

197 mph Chevrolet Corvette Stingray ZR1

258 mph Bugatti Veyron Supersport

195 mph Dodge Viper

270 mph Hennessey Venom

155 mph BMW M3

195 mph Mercedes SL

Write a function selectCars to identify cars with top speed within a given range and display the identified names. The selected cars speed will be in a range given by lowerBound < speed < upperBound. Inputs to the function selectCars are a column array topSpeeds that lists of top speeds, the corresponding column array carNames with car names, and lowerBound and upperBound both given in km/h.

Given:

To display the selected carNames, for example the first two, use something analogous to disp(carNames(1:2,:))

1 mile = 1.609 kilometers

Test data sets for topSpeeds and carNames (provided in example function call)

Restriction: For and while loops may not be used.

The function call is:

function identifiedCars=selectCars( topSpeeds, carNames, lowerBound, upperBound)

For example:

selectCars( topSpeeds, carNames, 287,338)

produces:

Ferrari 488

Nissan GTR

Chevrolet Corvette Stingray ZR1

Dodge Viper

Mercedes SL

CODE TO COPY:

function identifiedCars = selectCars( topSpeeds, carNames, lowerBound, upperBound)
% select cars that have top speed within a given range
% and display the names to the command line.
% Inputs: column array topSpeeds with top speeds in mile/hour,
%               corresponding column string array carNames with the car names
%               lowerBound and upperBound in km/h

    % convert the topSpeeds from mile/hour to km/h
    topSpeeds = topSpeeds*1.609;
  
    % find the logical index array for the desired cars
    logicalIndexArray = topSpeeds > lowerBound & topSpeeds < upperBound;
  
    % identify the car names that have top speed within a given range
    identifiedCars = carNames(logicalIndexArray,:);
  
    % display the car names to the command line
    disp(identifiedCars);
