数值积分 使用scipy库的integrate.quad函数来计算拟合曲线下的面积。 fromscipyimportintegrate# 计算拟合曲线下的面积area,_=integrate.quad(fit_func,0,10,args=params)print(f'The area under the fitted curve is:{area:.2f}') 1. 2. 3. 4. 5. 6. 4. 类图 在这里,我们可以想象出一个类展示了我们如...
最后,我们将函数的图像和曲线下方的面积可视化: x=np.linspace(a,b,100)# 生成从a到b的100个点y=f(x)# 计算这些点的y值plt.plot(x,y,label='f(x) = x^2')# 绘制函数曲线plt.fill_between(x,0,y,where=(x>=a)&(x<=b),alpha=0.5,label='Area under curve')# 填充曲线下面积plt.xlim(-0...
Since it is a Java-based programming language, you will be able to extend its applications beyond analytical research, analytical modelling, and statistical modelling. You will be able to create web applications using Python and integrate these web applications directly to your analytical models in t...
load_dataset("tips") # Create a density plot of the "total_bill" column from the "tips" dataset # We use the "hue" parameter to differentiate between "lunch" and "dinner" meal times # We use the "fill" parameter to fill the area under the curve # We adjust the "alpha" and "...
