To generate a Vandermonde matrix of the Hermite_e polynomial, use the hermite_e.hermvander() in Python Numpy. The method returns the pseudo-Vandermonde matrix. The shape of the returned matrix is x.shape + (deg + 1, ), where The last index is the degree of the corresponding Hermite polynomial. The dtype will be the same as the converted x.The parameter, x returns an Array of points. The dtype is converted to float64 or complex128 depending on whether any of the elements are complex. If x is scalar it is converted to a 1-D array. The parameter, deg is the degree of the resulting ... Read More

The pandas.Series.at attribute is used to access the single labeled element from a Series object and It is very similar to the loc in pandas. The “at” attribute takes label data to get or set the series value in that particular label position.It will return a single value based on the index label, and it also uploads the data at that particular label position.Example 1import pandas as pd # create a sample series s = pd.Series({'A':12, 'B':78, "C":56}) print(s) print(s.at['A'])ExplanationIn this following example, we have created a series using a python dictionary and the index will be ...

To return the Norm of the matrix or vector in Linear Algebra, use the LA.norm() method in Python Numpy. The 1st parameter, x is an input array. If axis is None, x must be 1-D or 2-D, unless ord is None. If both axis and ord are None, the 2-norm of x.ravel will be returned.The 2nd parameter, ord is the order of the norm. The inf means numpy’s inf object. The default is None. The "nuc" set as a parameter is the Nuclear norm. Both the Frobenius and nuclear norm orders are only defined for matricesStepsAt first, import the required ... Read More

The “.array” is one of the pandas series attributes. it will return a pandas ExtensionArray with the values stored in the series. The “.array” is used to get a zero-copy reference to the underlying data.The resultant array is not like a NumPy array it is an ExtensionArray, and it has different array types based on the data present in the series (dtype).Example 1import pandas as pd # create pandas series with numerical values s1 = pd.Series([1, 2, 3, 4]) print(s1) print(s1.array)ExplanationThe “s1” is the pandas series object which is created by using integer values with length 4. ...
