User can modify parameters by pulling the circle to adequate position or changing the valuesin the text eld directly.Figure 3.5: Result Display.Result Display displays results from analysis engine. This is a program written by Perland GD library. GD is a graphic library which is used for generating GIF format graph forour result pages. Figure 3.5 shows the Result Display.3.4 Program AlgorithmIn this section, we only describe the algorithm of analysis engine. This program parses eachequation and calculates value of each variable. We choose Perl as our programming languagebecause this language implements pattern match and powerful parser library.The data structure of each equation is as follow:struct equation {string *parameter;string *value;}40
If this equation is a function, for example f(x; y) =2x 2 + y, this function will be parsed tothis structure as follow: "f" is the structure name, "x; y" is the parameter and "2x 2 + y" isthe value. If this equation is just a scalar, for example C = Cm+ Cd+ Ct+ K, "C" will bethe structure name and "Cm + Cd + Ct + K" will be value. Because this kind of equationdoes not have parameters, a string "var" is stored in the parameters eld of the structure.Finally, the whole algorithm is listed as follows:calc{$equation){if($equation->value is a numerical value){return true;}else if($equation->parameters != "var")recurn false;}while($equation->value have non-numerical pattern){$pattern = extract_pattern($equation->value);if(calc($pattern)){replace $pattern to $pattern->value;} else { // this is a function$pattern_parameters = extract_fx($pattern);$fx_value = lookup_fx($pattern, $pattern_parameters);replace $pattern to $fx_value;}calculate $equation->value;}This program will recursively replace variables and functions in a equation untill the equationcontain only numerical value. Then, the value is gured out.41
