通过Matlab中的数据点拟合指数曲线 [英] Fit exponential curve through data points in Matlab

问题描述

有了指数衰减的数据，我想拟合一条曲线.如何在Matlab中做到这一点?

Having data of an exponential decay available, I would like to fit a curve through it. How can I do that in Matlab?

推荐答案

尝试一下:

ft=fittype('exp1');
cf=fit(time,data,ft)

这是当time和data是您的数据向量时；时间是自变量，数据是因变量.

This is when time and data are your data vectors; time is the independent variable and data is the dependent variable.

这将为您提供指数衰减曲线的系数.

This will give you the coefficients of the exponential decay curve.
