In robotic and graphic, we often need to rotate an object from one
position to another position. In this assignment, you will write a
FORTRAN'90 program that will read a square matrix [MAT(N,N)], and display
the original matrix and the following shapes according to user's entries:
a) the rotated matrix 90 degrees clockwise
exple: if N = 3 and
1 2 3 7 4 1
MAT = 4 5 6 the rotated matrix
is: 8 5 2
7 8 9 9 6 3
b) the rotated matrix 90 degrees counter-clockwise
exple: if N = 3 and
1 2 3 3 6 9
MAT = 4 5 6 the rotated matrix
is: 2 5 8
7 8 9 1 4 7
c) (bonus: 5 points) If you feel ambitious you might include functions
to rotate the matrix 45 deg., and/or move it around within the designated
portion of the first quadrant. Be creative!!.
- Make sure that your variable names are representative of their use.
- Remember that your program should work for any value of N
- Comment your program so someone else (TA!) can easily understand what
it does.
- Good luck.
Note:
This is the last FORTRAN 90 assignment - Turbo C is next!!
