Web在这里，我们旨在通过根据txt文件或dat文件中获得的状态拟合实验数据来确定参数。为了使用该函数，无论它是线性的还是非线性的，我们都使用一个名为curve_fit的模块，该模块是Python scipy包中包含的scipy.optimize模块的一部分。 线性功能配件. 首先，加载所需的 ... WebDec 29, 2024 · Of course, with np.polyfit we are not restricted to fitting lines, but we can fit a polynomial of any order if enough data points are available. The question is just if it makes sense. For instance, if we fit a polynomial of degree 10 to the data, we get the following result. coefs = np.polyfit(x_data, y_data, 10) poly = np.poly1d(coefs)
