This book consists of seven chapters,namely,the introduction,the solutions for non-linear equation,the interpolation method,the curve-fitting,the numerical differentiation and integration,the numerical solutions for differential equations,and the numerical solutions for algebra equation set.In order to an in-depth comprehension and application of the programming for the reader,it also presents a brief introduction to the MATLAB language basics in the form of appendix.It provides abundant questions concerning chemical industry application in each chapter.The CD attached embraces all the programming of the examples.As the chemical computing is comparatively complex,it is necessary to use the computer to seek for the solutions for those students and technologists engaged in chemical industry.
