Python | Numpy np.chebmul() method Last Updated : 03 Nov, 2019 Comments Improve Suggest changes Like Article Like Report With the help of np.chebmul() method, we can get the multiplication of two Chebyshev series by using np.chebmul() method. Syntax : np.chebmul(s1, s2) Return : Return an array after multiplication. Example #1 : In this example we can see that by using np.chebmul() method, we are able to get the multiplication of two chebyshev series using this method. Python3 1=1 # import numpy import numpy as np from numpy.polynomial import chebyshev as C s1 = (4, 6, 8) s2 = (3, 5, 7) # using np.chebmul() method gfg = C.chebmul(s1, s2) print(gfg) Output : [55. 79. 67. 41. 28.] Example #2 : Python3 1=1 # import numpy import numpy as np from numpy.polynomial import chebyshev as C s1 = (4, 6, 8, 1, 3, 5) s2 = (3, 5, 7, 2, 4, 6) # using np.chebmul() method gfg = C.chebmul(s1, s2) print(gfg) Output : [ 77. 114.5 110. 113. 92. 70. 58. 46.5 14. 19. 15. ] Comment More infoAdvertise with us Next Article Python | Numpy np.chebmul() method J Jitender_1998 Follow Improve Article Tags : Technical Scripter Python Python-numpy Python numpy-arrayManipulation Practice Tags : python Similar Reads Python | Numpy np.chebmulx() method With the help of np.chebmulx() method, we can get the multiplication of Chebyshev series with independent variable x by using np.chebmulx() method.
