Numerical analysis: the second question into command files, including factorial can separate into function calls in the command file, file of command can also directly in your file calculated directly by using the loop statement;
The fourth question is a general procedure, which is recommended to be composed of functional documents. Tip: you can set the coefficients of polynomials and the points you need to solve as parameters. - Numerical Analysis of requirements: the second title of the command file can be compiled, which can factorial function into a separate file in order to call the document can also be made directly in your document, use the command loop direct calculation into fourth title common procedures, the programs the document into the function. The Tip: polynomial coefficients can be requested and the required parameters set point solution.
