解决数值计算、科学绘图等科学和工程问题的一般步骤是:先利用Fortran、C或Pascal等计算机语言进行编程,再经过调试,最后得到结果。这种方法要求计算者对所运用的计算机语言具有一定的编程能力。本文以分析化学中的pH计算、型体曲线绘制和滴定曲线绘制为例,讨论了MATLAB在分析化学中的应用。并由此想到能否参照其它的工具箱编制用于分析化学的MATLAB的M函数库。结果表明,这种方法简单实用,效率高,数值稳定性好。
The general steps to solve scientific and engineering problems such as numerical calculations and scientific drawings are: first programming in a computer language such as Fortran, C, or Pascal, then debugging, and finally the result. This method requires that the computer has some programming power over the computer language used. In this paper, the analytical chemistry of the pH calculation, the body curve and titration curve drawn as an example, discussed the application of MATLAB in analytical chemistry. And so came up with the idea of using other toolkits to build M functions libraries for analytical chemistry. The results show that this method is simple and practical, high efficiency and good numerical stability.
