def model_func(t, a, b, c):

Question

I am fitting a function to a power law by using

def model_func(t, a, b, c):                                                         
    return a * np.exp(-b * t) + c  

opt_parms, parm_cov = sp.optimize.curve_fit(model_func, x1, y1, maxfev=1000)          
a,b,c = opt_parms

The fitted curve looks perfect, but how can I get the exact function printed (like y=a*b^x)?

Thanks in advance

Thanks that worked, but it is not `Y={0}*{1}^x+{2}".format(a,b,c)` but `Y={0}*{1}^(x/10)+{2}".format(a,b,c)` how does that come?? — user3113106, Dec 17 '13 at 23:39

If you have your fit variables in a, b, and c, you can just print them…

print('y = {} * -{} t + {}'.format(a, b, c))
