Fortran problem: Need help. --- Anyone speak this dead language?
Posted on 2006-04-13
Hi, I know this is a C forum, however I have a Fortran question. I guess this is the closest I will get to this ancient language. I am trying to help out a kid who has this assignment. The teacher is making him write it in fortran. Could anyone give us any help with it? The old language I have worked with is C. Thanks
PROBLEM: Solution of simultaneous linear equations using matrices and Cramer’s rule.
GIVEN: Several pairs of linear equations of the form Ax + By = E, and Cx + Dy = F. The coefficients A, B, C, D, and F may have up to five digits including two decimal places.
REQUIRED: A flowchart for FORTRAN program to arrive at the different possible solutions for the pairs of linear equations.
A printout of the .LST file for your program showing no errors.
A printout of the solution to each pair of equations. The solutions for your printout will be for the following coefficients:
A B C D E F
1.0 3.0 -2.0 4.0 2.0 5.0
2.0 4.0 3.0 6.0 1.0 4.0
-2.0 3.0 1.0 8.0 0.0 0.0
2.0 4.0 3.0 6.0 1.0 1.5
-3.0 2.0 1.0 2.0 -2.0 6.0
3.2 6.7 5.4 1.8 0.9 3.2
Your program should include sufficient alphanumeric information to identify the different possible solutions for simultaneous linear equations.
