Python | Numpy np.chebval2d() method Last Updated : 11 Nov, 2019 Comments Improve Suggest changes Like Article Like Report With the help of np.chebval2d() method, we can get the array of coefficients after evaluation on (x, y) on chebyshev series by using np.chebval2d() method. Syntax : np.chebval2d(x, y, c) Return : Return an array after evaluation on (x, y). Example #1 : In this example we can see that by using np.chebval2d() method, we are able to get the array of coefficients by evaluating (x, y) on chebyshev series. Python3 1=1 # import numpy import numpy as np import numpy.polynomial.chebyshev as cheb # using np.chebval2d() method gfg = cheb.chebval2d((2, 5), (1, 3), (2, -4, 1)) print(gfg) Output : [32. 94.] Example #2 : Python3 1=1 # import numpy import numpy as np import numpy.polynomial.chebyshev as cheb # using np.chebval2d() method gfg = cheb.chebval2d((1, 3, 5, 7), (2, 4, 8), (2, -4, 1, 5, 1)) print(gfg) Output : [719680. 6486180. 52831708.] Comment More infoAdvertise with us Next Article Python | Numpy np.chebval2d() method J Jitender_1998 Follow Improve Article Tags : Technical Scripter Python Python-numpy Practice Tags : python Similar Reads Python | Numpy np.chebval() method With the help of np.chebval() method, we can get the array of coefficients after evaluation of x on chebyshev series by using np.chebval() method.
