TypeError: _linspace_dispatcher() missing 1 required positional argument: 'stop' - Ae_Lovecraft - May-27-2020 I'm triying to make a double reimann sum, with a limit b = (x^2 + y^2 = 16), the problem is when I use Sympy and marks as a TypeError in the linespace column, I tried to def the ecuation but nothing works, I'm doing somethin wrong or should I change something? import numpy as np import matplotlib.pyplot as plt import sympy # function to integrate = x +3*y + 1 # Limit funtion 'b' =(x^2 + y^2 = 16) Width=15; Length=20; x = sympy.Symbol('x') a = 0 b =(sympy.sqrt(16-x**2)) c = 0 d = 3 #Heigth of x deltax= (b - a) / Width #Heigth of y deltay = (d - c) / Length #Area of each square dA = deltax * deltay x = np.linspace((a, b - deltax, Ancho)); y = np.linspace((c, d - deltay, Largo)); f = lambda x,y: x +3*y + 1 [X, Y] = np.meshgrid(x, y); #reimann sum Suma=sum(dA * f(X, Y)) Suma = sum(Suma) int(Suma) print(Suma)
RE: TypeError: _linspace_dispatcher() missing 1 required positional argument: 'stop' - Larz60+ - May-27-2020 Ancho, Largo Not defined RE: TypeError: _linspace_dispatcher() missing 1 required positional argument: 'stop' - Ae_Lovecraft - May-28-2020 Sorry it was a typo error, but my code stills send the same error Ancho = Width and Largo = Length ** RE: TypeError: _linspace_dispatcher() missing 1 required positional argument: 'stop' - Larz60+ - May-28-2020 linspace syntax: numpy.linspace(start, stop, num=50, endpoint=True, retstep=False, dtype=None, axis=0) why double parenthesis, whole command? unlikely a cuase, but add parenthesis around b - deltax and d - deltay also, just before command, print out values of b - deltax and d - deltay |
