John Halleck's Cave Survey Code in C:


Programs

Available programs.

DISCLAIMER

No warranty, express or implied, should be assumed for these code fragments. They are for educational and demonstration purposes, and may contain major errors.

Notes

None.

Dependencies

These programs all use the package wide error routines.

Notes

These programs print an error message if they have trouble, and return the error code for whatever was wrong. If all went well, they return 0.

Programs

Not much here. The following two programs were just written to allow me to have something to compute inverses for various examples in the text.

invert22

Invert a given 2x2 matrix.

invert33

Invert a given 3x3 matrix.

invert44

Invert a given 4x4 matrix.

demo1

Do a full network adjustment, given the change in X, Y, and Z for each shot, and the weights.

There is test data (which serves as good examples of input format) located in demo1-testdata.txt.

Miscellaneous

More programs are going to be added as they are written/debugged.
