expfit: fit exponential function to data

tesfdmtools.methods.expfit.expfit(x, y, yerr=None, debug=False)

fit exponential function y=a*exp(b*x)+c

Args:

• x = x values

• y = y values to be fitted

Kwargs:

• yerr = sigma errors of the y-values

• debug = when True, print/plot debug information when fit does not converge

Returns:

• p = fitted parameter values for the function y=p[0]*exp(p[1]*x)+p[2]

• yfit = fitted function values
