具体解释如下： 1. 获取股票数据 python df = ts.get_k_data('600519', start='2001-01-01', end='2015-12-31') 这行代码使用tushare库获取股票代码为'600519'的数据，时间范围从2001-01-01到2015-12-31。...

解释这段代码每行的意思：for i in range(0, len(x_valid)): N = 1024 fs = 12000 t = np.linspace(0, 1024 / fs, N, endpoint=False) wavename = 'cmor3-3' totalscal = 256 fc = pywt.central_frequency(wavename)#中心频率 cparam = 2 * fc * totalscal scales = cparam / np.arange(totalscal, 1, -1) [cwtmatr, frequencies] = pywt.cwt(x_valid[i], scales, wavename, 1.0 / fs) plt.contourf(t, frequencies, abs(cwtmatr)) plt.axis('off') plt.gcf().set_size_inches(1024 / 100, 1024 / 100) plt.gca().xaxis.set_major_locator(plt.NullLocator()) plt.gca().yaxis.set_major_locator(plt.NullLocator()) plt.subplots_adjust(top=1, bottom=0, right=1, left=0, hspace=0, wspace=0) plt.margins(0, 0) x = r'./cwt_picture/valid/' + str(i) + '-' + str(y_valid[i]) + '.jpg' plt.savefig(x) plt.clf() plt.close()

这段代码的含义是：对于x_valid的长度，从0遍历到其长度-1，每次循环执行以下操作：设定N为1024，fs为12000，用np.linspace生成长度为N的时间向量t，wavename为'cmor3-3'，totalscal设定为256，fc为通过pywt库计算...
