GAUSS blog: Diagnosing a singular matrix
This code accompanies the Aptech blog Diagnosing a singular matrix which was published on 11/25/2018.
The program files require a working copy of GAUSS 18+. Many can be run on earlier versions with some small revisions.
Three program files are included:
- singular_model.e - This file contains the model which results in a singular matrix error.
- diagnostics.e - This file contains diagnostic tests for finding the cause of the singular matrix.
- final_model.e - This file contains the final model which remedies the singular matrix issues based on the diagnostic testing.
- golf_ballflight.csv - This file contains the data used in singular_model.e, diagnostics.e and final_model.e.
