The toolbox solves a variety of approximate modeling problems for linear static models. The model can be parameterized in kernel, image, or input/output form and the approximation criterion, called misfit, is a weighted norm between the given data and data that is consistent with the model. There are three main classes of functions in the toolbox: transformation functions, misfit computation functions, and approximation functions. The approximation functions derive an approximate model from data, the misfit computation functions are used for validation and comparison of models, and the transformation functions are used for deriving one model representation from another. KEYWORDS: Total least squares, generalized total least squares, software implementation.

This a simple database management system. It doesn t use any other code (i.e. ODBC, ADO, etc.) and has it s own database file format. I wrote it because I found the other DBMSs code too bulky and hard to debug. It s designed for small applications and I doubt it could handle anything on a large scale. A sample program included in the .zip shows how everything works. The database project is a library project, so you ll have to compile and link with the .lib file to get everything working. Pros: - You have the source code so you know exactly what it is doing - Database files are very small - Small and fast code Cons: - Can t handle large amounts of records (more than 65000ish) - Doesn t support SQL (you have to search the database by cycling through the records and testing them against your constraints) - Each database file can only have one table.
