To evaluate a 3D Legendre series at points x, y, z use the polynomial.legendre.legval3d() method in Python Numpy. The method returns the values of the multidimensional polynomial on points formed with triples of corresponding values from x, y, and z.If c has fewer than 3 dimensions, ones are implicitly appended to its shape to make it 3-D. The shape of the result will be c.shape[3:] + x.shape. The 1st parameter is x, y, z. The three dimensional series is evaluated at the points (x, y, z), where x, y, and z must have the same shape. If any of x, ... Read More

To evaluate a Legendre series at array of points x, use the polynomial.legendre.legval() method in Python Numpy. The 1st parameter is x. If x is a list or tuple, it is converted to an ndarray, otherwise it is left unchanged and treated as a scalar. In either case, x or its elements must support addition and multiplication with themselves and with the elements of c.The 2nd parameter, C, an array of coefficients ordered so that the coefficients for terms of degree n are contained in c[n]. If c is multidimensional the remaining indices enumerate multiple polynomials. In the two dimensional ... Read More

The series.eq() method in the pandas constructor is used to compare elements of the given series with others (maybe another series or a scalar value). As a result, It will return a new series object with boolean values.The element-wise equal operation is done by using this eq() method. The boolean value True represents the equivalent value in the second series object. And remaining unequal values are represented by the boolean value False.The parameters of the eq() method are other, fill_value, and level.Example 1In the following example, we will see how the eq() method compares elements of a series object with ...

To raise a Legendre series to a power, use the polynomial.legendre.legpow() method in Python Numpy. The method returns the Legendre series c raised to the power pow. The argument c is a sequence of coefficients ordered from low to high. i.e., [1, 2, 3] is the series P_0 + 2*P_1 + 3*P_2. Returns the Legendre series c raised to the power pow. The argument c is a sequence of coefficients ordered from low to high. i.e., [1, 2, 3] is the series P_0 + 2*P_1 + 3*P_2.The parameter, c is a 1-D array of Legendre series coefficients ordered from low ...

By using the duplicated() method in the pandas series constructor we can easily identify the duplicate values in the index of a series object. The method duplicated() is used to identify the duplicate values in a series object.The duplicated() method will return a series with boolean values. Boolean value False indicates single occurrence values mean unique values. The duplicated values are indicated with boolean value True.Example 1Here we will see how we can delete the rows of a series object with duplicate indices.# importing pandas package import pandas as pd #create series series = pd.Series(["a", "b", "c", "d", "e"], ...

To integrate a Hermite series, use the hermite.hermint() method in Python. The 1st parameter, c is an array of Hermite series coefficients. If c is multidimensional the different axis correspond to different variables with the degree in each axis given by the corresponding index.The 2nd parameter, m is an order of integration, must be positive. (Default: 1). The 3rd parameter, k is an integration constant(s). The value of the first integral at lbnd is the first value in the list, the value of the second integral at lbnd is the second value, etc. If k == [] (the default), all ... Read More

Finding the duplicate values in an object is a very common task in the data analysis process. In pandas, we have a function called duplicated() which is used to identify the duplicate values.For a pandas series object, the duplicated() method will return a series with boolean values. True indicates duplicate values only for the last occurrence values or the first occurrence values or it may indicate all the duplicate values.The duplicated() method has a parameter called “keep” which is used to treat the duplicate values differently. The default behavior of this parameter is “first” which means it marks all the ... Read More
