7、合分为fit(xdata,ydata,exp1)和fit(xdata,ydata,exp2),分别为单指数和双指数拟合。例如TRV的工频拟合和拟合系数的选取:>> temp gof=fit(x',y','exp2')temp = General model Exp2: temp(x) = a*exp(b*x) + c*exp(d*x) Coefficients (with 95% confidence bounds): a = 421.6 (395.4, ...

This tool computes a linear fit when there are uncertainties in x data and y data. The best slope and intercept are computed by minimizing the chi2 calculated using both standard deviation on x and y (Deming fit). Data points are simulated using a Monte Carlo method so as to obtain ...

Something doesn't work for me in fit by Yohay Yohay has been working on a simulation to measure particle speed and fit it to the Maxwell-Boltzmann distribution. However, the fit isn't aligning perfectly with the data. Yohay has shared the code and histogram data for community members to re...
