Python sns.distplot(d,fit=stats.laplace,kde=False) Again, note the slight difference. In the first case, you’re estimating some unknown PDF; in the second, you’re taking a known distribution and finding what parameters best describe it given the empirical data. ...

Althoughnumpy.linspaceinherently generates a 1D array in Python, we can easily reshape it to 2D or use it in combination with other functions to create 2D arrays in Python. import numpy as np two_d_array = np.linspace(0, 1, num=20).reshape(4, 5) ...
The global functions reuse a single global gnuplotlib instance, so each such invocation rewrites over the previous gnuplot window.The object-oriented interface is used like this:import gnuplotlib as gp g = gp.gnuplotlib(options) g.plot( curve, curve, ... )The...
Use of Special Libraries There are libraries that can be used to generate arrays for special purposes and it isn’t possible to enumerate all of them. The most common uses are use of the many array generation functions in random that can generate arrays of random values, and some utility ...
