Evaluate a 3-D Chebyshev series at points (x, y, z) with 4D array of coefficient in Python
To evaluate a 3-D Chebyshev series at points (x, y, z), use the polynomial.chebval3d() 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. Syntax numpy.polynomial.chebyshev.chebval3d(x, y, z, c) Parameters The function accepts the following parameters − 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, y, or z is a list or tuple, it ...

To evaluate a 2-D Chebyshev series at points (x, y), use the polynomial.chebval2d() method in Python NumPy. The method returns the values of the two dimensional Chebyshev series at points formed from pairs of corresponding values from x and y. The parameter c is an array of coefficients ordered so that the coefficient of the term of multidegree i, j is contained in c[i, j]. If c has dimension greater than 2, the remaining indices enumerate multiple sets of coefficients.

To evaluate a Chebyshev series at points x with multi-dimensional coefficients, use the chebyshev.chebval() method in NumPy. This method handles coefficient arrays where each column represents a different polynomial series. Syntax numpy.polynomial.chebyshev.chebval(x, c, tensor=True) Parameters x: Points at which to evaluate the series. Can be scalar, list, or array. c: Array of coefficients. For multi-dimensional arrays, each column represents a separate polynomial. tensor: If True (default), evaluates every column of coefficients for every element of x. If False, broadcasts x over the columns. Example Let's create a 2D coefficient array ...
