Given an input array of strings (characters) s, pick out the second column of data and convert it into a column vector of data.
hodyreva [135]

Answer:

Consider the following code.

Explanation:

save the following code in read_and_interp.m

 

function X = read_and_interp(s)

[m, n] = size(s);

X = zeros(m, 1);

for i = 1:m

if(str2num(s(i, 2:5)) == 9999)

% compute value based on previous and next entries in s array

% s(i, 2:5) retrieves columns 2-5 in ith row

X(i,1) = (str2num(s(i-1 ,2:5)) + str2num(s(i+1,2:5)))/2;

else

X(i,1) = str2num(s(i,2:5));

end

end

end

======================

Now you can use teh function as shown below

s = [ 'A' '0096' ; 'B' '0114' ; 'C' '9999' ; 'D' '0105' ; 'E' '0112' ];

read_and_interp(s)

output

ans =

96.000

114.000

109.500

105.000

112.000

The chart shows changes in sea level from 1995 to 2013. According to the chart, sea levels rose at an average annual rate of 3.2
MariettaO [177]

Answer:

Did the global surface temperature increase steadily from 1995 to 2013?

Did sea ice extent in polar regions reduce because of melting from 1995 to 2013?

Explanation:

Only two questions are directly related to global warnings increasing sea levels:

  • Did the global surface temperature increase steadily from 1995 to 2013? Increasing temperature of the Earth's surface is actually what warming means.
  • Did sea ice extent in polar regions reduce because of melting from 1995 to 2013? If the polar ice melts then the sea levels will rise.

The other three questions were about the negative effects of rising sea levels, but not what could cause them.

Now that the classList Array has been implemented, we need to create methods to access the list items.
natima [27]

The following code will be applied to Create the following static methods for the Student class

<u>Explanation:</u>

/* Note: Array index starts from 0 in java so ,, user ask for 1 index then the position will be i-1 , below program is based on this concept if you dont want this way just remove -1 from classList.get(i-1).getName(); ,and classList.add(i-1,student); */

/* ClassListTester.java */

public class ClassListTester

{

public static void main(String[] args)

{

//You don't need to change anything here, but feel free to add more Students!

Student alan = new Student("Alan", 11);

Student kevin = new Student("Kevin", 10);

Student annie = new Student("Annie", 12);

System.out.println(Student.printClassList());

System.out.println(Student.getLastStudent());

System.out.println(Student.getStudent(1));

Student.addStudent(2, new Student("Trevor", 12));

System.out.println(Student.printClassList());

System.out.println(Student.getClassSize());

}

}

/* Student.java */

import java.util.ArrayList;

public class Student

{

private String name;

private int grade;

//Implement classList here:

private static ArrayList<Student> classList = new ArrayList<Student>();

public Student(String name, int grade)

{

this.name = name;

this.grade = grade;

classList.add(this);

}

public String getName()

{

return this.name;

}

//Add the static methods here:

public static String printClassList()

{

String names = "";

for(Student name: classList)

{

names+= name.getName() + "\n";

}

return "Student Class List:\n" + names;

}  

public static String getLastStudent() {

// index run from 0 so last student will be size -1

return classList.get(classList.size()-1).getName();

}

public static String getStudent(int i) {

// array starts from 0 so i-1 will be the student

return classList.get(i-1).getName();

}

public static void addStudent(int i, Student student) {

// array starts from 0 so, we add at i-1 position

classList.add(i-1,student);

// remove extra student

classList.remove(classList.size()-1);

}  

public static int getClassSize() {

return classList.size();

}

}
