Using Java and the game-math library named GM2D03 , or using a different programming environment of your choice, write a program that createsfour column matrix objects using the following names and values:
Then use matrix addition and subtraction to compute and display the values of the following matrices:
Finally, test matE and matF for equality and display the result, replacing the question mark with either true or false..
Cause the program to display your name in some manner.
My version of the program produces the text output shown in Figure 4 , and you should use that as a display template.

Using Java and the game-math library named GM2D03 , or using a different programming environment of your choice, write a program that createsand displays (in text form) three vectors having the names and values shown in Figure 5 .
Cause your program to test vecA for equality, first against vecB , and then against vecC , and display the results of the tests in place of the question marks shown in Figure 5 .

Using Java and the game-math library named GM2D03 , or using a different programming environment of your choice, write a program that createsand displays four column matrices having the names and values shown in Figure 6 .
Use the first two matrices to create a displacement vector named dispVecE and display its value in place of the question marks in Figure 6 .
Use the last two matrices to create another displacement vector named dispVecF and display its value in place of the question marks in Figure 6 .
Test dispVecE and dispVecF for equality and display the result of the test in place of the final question mark in Figure 6 .
