Suppose the Texas Department of Motor Vehicles is tracking the number of car, truck and motorcycle (respectively) crashes in Texas over the years 2000 to 2019 in an array TXCrash (3 x 20).


Write code to define a MATLAB variable that contains the number of truck crashes for the year 2019.

Answer #1

Solution in Matlab:

TXCrash = zeros(3,20); #Line1
TXCrash = randi([0,100],size(TXCrash)); #Line2
TXCrash_truck_2019 = (TXCrash(2,end)); #Line3

Line1: Its declaring an array of 3 rows and 20 columns where Rows are Car,Truck and Motorcycle respectively and columns are years from 2000 to 2019 with zeroes.

Line2: Its putting a 3*20 array(since TXCrash is also 3*20) of pseudorandom integers between 0 and 100.

Line3: This line will put the last value from 2nd row i.e Truck Crash for the year 2019.

    Suppose we have data on the number of U.S. recruits who were rejected for service in a war against Spain because they did not have enough teeth. We wish to compare the rejection rate for recruits who were under the age of 20 with the rate for those who were 40 or over. To run a logistic regression for this setting, we define an indicator explanatory variable x with values 0 for age under 20 and 1 for age 40...

    This C++ Program consists of: operator overloading, as well as experience with managing dynamic memory allocation inside a class. Task One common limitation of programming languages is that the built-in types are limited to smaller finite ranges of storage. For instance, the built-in int type in C++ is 4 bytes in most systems today, allowing for about 4 billion different numbers. The regular int splits this range between positive and negative numbers, but even an unsigned int (assuming 4 bytes)...
