A 16-bit microcomputer (PC/AT) can control complex experiments, collect large quantities of data, display the raw information, perform computations and display transformed data in real time. A mathematical modeling language "DAL" developed by Brian Collett can perform much of the same kind of analyses provided by MLAB. A test case employed a data matrix with approximately 15000 numbers in double precision (approximately 120000 bytes). These data were subjected to SVD and the simultaneous fitting, with weights, of 47 parameters to 6 columns of data. The time to accomplish this was as fast as that used on the DEC 10 system and the results were the same. However, in order to use "DAL" a user must be proficient in partial differential equations and computer programming. For this reason, it is recommended that scientists wait 1 to 2 years until a revised form of MLAB will be available for use on PC's. An independent effort by LAS of DCRT has been centered on the use of the 32 bit personal work station provided by a Sun microcomputer. The mathematical modeling has been performed with "PC MATLAB". Similar problems for the scientist are presented with this package, as were cited above for "DAL".

16位微机（PC/AT）可控制复杂的实验， 收集大量数据，显示原始信息， 执行计算并实时显示转换后的数据。 Brian Collett 开发的数学建模语言“DAL” 可以执行 MLAB 提供的大部分同类分析。 测试用例使用了大约 15000 个数字的数据矩阵 双精度（大约 120000 字节）。 这些数据是 进行 SVD 和同时拟合，权重为 47 参数为6列数据。 完成此任务的时间是 与 DEC 10 系统上使用的速度一样快，结果是 相同的。 但是，为了使用“DAL”，用户必须精通 偏微分方程和计算机编程。 为了这 原因是，建议科学家等待1到2年，直到 MLAB 的修订版将可在 PC 上使用。 一个 DCRT 的 LAS 的独立努力集中于使用 由Sun微机提供的32位个人工作站。 使用“PC MATLAB”进行数学建模。 这个包也给科学家提出了类似的问题， 如上面引用的“DAL”。
