How to do exponential and logarithmic curve fitting in Python? I found only polynomial fitting
...c):
return a * np.exp(-b * x) + c
x = np.linspace(0,4,50)
y = func(x, 2.5, 1.3, 0.5)
yn = y + 0.2*np.random.normal(size=len(x))
popt, pcov = curve_fit(func, x, yn)
And then if you want to plot, you could do:
plt.figure()
plt.plot(x, yn, 'ko', label="Original Noised Data")
plt.plot(x, func(x...
StringIO in Python3
...ou should avoid six and just import from io instead.
If you support Python 2.5 or lower and 3.x: You'll need StringIO.StringIO for 2.5 or lower, so you might as well use six. But realize that it's generally very difficult to support both 2.5 and 3.x, so you should consider bumping your lowest suppor...
What is more efficient? Using pow to square or just multiply it with itself?
...
i*i: 0.000352s (result = 3.33333e+07)
std::pow(i,3): 0.006034s (result = 2.5e+07)
i*i*i: 0.000328s (result = 2.5e+07)
With optimisation, the results were equally striking:
std::pow(i,2): 0.000155s (result = 3.33333e+07)
i*i: 0.000106s (result = 3.33333e+07)

Why em instead of px?

}
* { margin: 0; padding: 0; font-size: 10pt; }
// Initial width of date-box = 10 pt x 2.5 em = 25 pt
// Will also work if you used px instead of pt
That way you have a fluid design on the date-box, i.e. the box wi...
