I`m a student at Universidad de Buenos Aires, currently studying Physics. I don`t know what to write to earn the badge so I`ll just fill it up with this sentence. Also, I`ll embed this code for no reason: from lmfit import Minimizer, Parameters, report_fit import matplotlib.pyplot as plt w1, V1, phi1, scal1 = np.loadtxt(./FiltroPasaBajo_1.txt, delimiter = t, unpack = True) t = w1 eV= V1*0.03 + 0.01 def funcion(parametros, x, y): R = parametros[`R`].value C = parametros[`C`].value modelo = 4/((1+(x**2)*(R**2)*(C**2))**1/2) return modelo - y parametros = Parameters() parametros.add(`R`, value = 1000, min= 900, max = 1100) parametros.add(`C`, value = 1E-6, min = 1E-7, max = 1E-5) fit = Minimizer(funcion, parametros, fcn_args=(t,V1)) resultado = fit.minimize() final = V1 + resultado.residual report_fit(resultado) try: plt.plot(t, V1, `k+`) plt.plot(t, final, `r`) plt.show() except ImportError: pass ©
