摘要
为了便于快速地找到适用的曲线拟合方法,以半导体热敏电阻实验中温度曲线的曲线拟合为例,全面地总结了利用Matlab程序进行曲线拟合的基本理论和具体方法,演示了lsqcurvefit、nlinfit和fit三个非线性拟合指令的具体程序格式与操作步骤。这些Matlab指令程序可以有效地应对实验数据处理中各种复杂的曲线拟合问题。
To find an appropriate curve-fitting method quickly,taking the curve fitting of the temperature curve of a semiconductor thermistor as an example,the basic theory and method of curve fitting using Matlab programs are summarized comprehensively.The program format and operation steps of three non-linear fitting instructions, lsqcurvefit,nlinfit and fit,are demonstrated.These MATLAB instruction programs can effectively deal with various complex curve fitting problems in experimental data processing.
