For this example, the final result can be obtained by use of either an analog or digital computer. The details for obtaining the solution with a digital computer using the three computer languages of FORTRAN, BASIC, and PASCAL are presented in the following + Tables 13, 14, and 15 provide the... 

If you are familiar with computer languages such as BASIC or FORTRAN, you will find yourself quite comfortable with most of the material in this section. 

Expert systems can be developed using either conventional computer languages, special purpose languages, or with the assistance of development shells or tool-kits. Conventional languages such as PASCAL and C have the advantages of wide applicability and full flexibility to create the control and inferencing strategies required. They also are well supported and easy to customize. However, considerable amounts of time and effort are needed to create the basic facilities. 

A computer cannot perform any task by itself. Like a car without gas, a computer has potential, but without a program, it isn t going anywhere. Most of the programs published in this book are written in a computer language called BASIC. BASIC is easy to learn and is built into the Commodore 128 in both 128 and 64 modes. 

This chapter has shown how composite data types can be of great use in chemical databases. The components of a composite data type are either basic SQL data types, or other composite data types. This is the same way an object is defined in an object-oriented computer language. This level of abstraction can help simplify the development of complex databases. 

As you can see, matrix multiplication with fairly large matrices can involve a lot of computation. Computer programs can be written to carry out the process, and such programs are built into Mathematica and also into computer languages such as BASIC so that a matrix multiplication can be carried out with a single statement. 

The solution is represented by a column vector that is equal to the matrix product A C. In order for a matrix to possess an inverse, it must be nonsingular, which means that its determinant does not vanish. If the matrix is singular, the system of equations cannot be solved because it is either linearly independent or inconsistent. We have already discussed the inversion of a matrix in Chapter 9. The difficulty with carrying out this procedure by hand is that it is probably more work to invert an n by n matrix than to solve the set of equations by other means. However, with access to Mathematica, BASIC, or another computer language that automatically inverts matrices, you can solve such a set of equations very quickly.
