MLAB ENHANCED FOR THE MACINTOSH WITH GRAPHICAL EXTENSION

MLAB交互式数学建模语言旨在为 生物医学研究人员。它已经由文明软件实现 用于IBM兼容的个人计算机。MLab可用于执行 复杂的数学和统计计算，包括曲线 用简单、直接的方法对微分方程模型进行拟合 计算命令。函数、数据和计算结果可以 使用强大的图形命令在屏幕上以图形方式显示。 这样构建的图形也可以转换为磁盘文件，用于 传送到Postscript激光打印机，以便包含在一个单词中- 处理文档，允许收录在科学文章中。MLab有 在与健康相关的研究中表明自己是必不可少的，正如其 在数百种出版物中使用，并在 美国国立卫生研究院、医学研究机构和 制药公司。 这项提议的目标是转换和加强MLAB计划 在Apple Macintosh II系列计算机上运行。虽然首字母是 第一阶段要进行的转换将相当于PC 计划在大多数方面，第二阶段的产品将有新的功能， 包括动画图形，并完全融入了Macintosh 图形用户界面，以增加功能并简化使用 MLab计划。 对于第一阶段，我们还将设计(视修改和增强而定 在第二阶段期间)对MLAB的一些扩展利用了 Macintosh图形用户界面。 这些功能将包括可操作的图形窗口，允许 要使用鼠标和下拉菜单编辑的图形以更改字体， 文本标签的大小、颜色和位置，以调整 图表，并制作硬拷贝。在图中，曲线可能是 以鼠标识别为目的进行删除、提取 信息，删除可疑数据，以及更改颜色， 打印字符和标签。

The MLAB interactive mathematical modeling language is intended to serve biomedical researchers. It has been implemented by Civilized Software for IBM-compatible personal computers. MLAB may be used to perform complex mathematical and statistical calculations, including curve fitting to differential equation models, by means of simple, direct computational commands. functions, data, and computational results may be displayed graphically on screen using powerful graphics commands. Graphs so constructed may also be converted to a disk file for transmission to a Postscript laser printer for inclusion in a word- processing document, allowing inclusion in scientific articles. MLAB has shown itself essential in health-related research, as demonstrated by its use in hundreds of publications, and continuing interest in its use at the National Institutes of Health, medical research institutions, and pharmaceutical companies. The objective of this proposal is to convert and enhance the MLAB program to run on the Apple Macintosh II family of computers. while the initial conversion to be carried out for Phase I will be equivalent to the PC program in most ways, the Phase II product will have new features, including animated graphics, and fully incorporate the Macintosh graphical user interface to increase the power and simplify use of the MLAB program. For Phase I we will also design (subject to revision and enhancement during Phase II) some of the extensions to MLAB which take advantage of the Macintosh graphical user interface. These features will include manipulable graphics windows which permit graphs to be edited using the mouse and pull-down menus to change font, size, color, and position of text labels, to re-size and re-window the graphs, and to produce hard copy. Within graphs, curves may be identified with the mouse for the purpose of deletion, extracting information, removing suspicious data, as well as changing color, plotting characters, and labels.
