WebFeb 23, 2024 · 0. I am trying to fit some data using a stretch exponential function of type : c* (exp (-x/tau)^beta). The value I am interested in is tau. The data I am trying to fit passes through zero and is also negative sometimes (For example, value goes from -1 to 1). def st_exp (x,c,tau,beta): return c* (np.exp (- (x/tau)**beta))
Stretched exponential function - HandWiki
Webthis exponential form will not t the magnetization recov-ery data well, making it di cult to extract a meaningful value of T 1 1. It is common practice to t the recovery to a stretched exponential form, exp[ (t=T 1) ], where is the so-called stretching exponent that provides a rough measures of the width of P(W 1), and satis es 0 < 1 [22,23]. WebThe stretched exponential function. is obtained by inserting a fractional power law into the exponential function.In most applications, it is meaningful only for arguments t between 0 and +∞. With β = 1, the usual exponential function is recovered.With a stretching exponent β between 0 and 1, the graph of log f versus t is characteristically stretched, whence the … kusmi tea coffret
