As an AI language model, I don't have access to the file "StockFinanceA.xlsx" and cannot execute this code. However, I can explain what this code does.
The code uses the function "xlsread" to read data from the Excel file "StockFinanceA.xlsx" in the range "AL3:AZ4736". The data is then stored in a variable "x".
The range "AL3:AZ4736" in the Excel file likely contains financial data such as stock prices, earnings, or other financial metrics. The variable "x" can then be used in further calculations or analysis.

[data1,~,~] = xlsread('20230504.xlsx','sheet1','A4:B9799'); [data2,~,~] = xlsread('20230504.xlsx','sheet1','C4:D5756'); [data3,~,~] = xlsread('20230504.xlsx','sheet1','E4:F5724'); [data4,~,~] = xlsread('20230504.xlsx','sheet1','G4:H5734'); [data5,~,~] = xlsread('20230504.xlsx','sheet1','I4:J5730'); [data6,~,~] = xlsread('20230504.xlsx','sheet1','K4:L5703'); [data7,~,~] = xlsread('20230504.xlsx','sheet1','M4:N5716'); [data8,~,~] = xlsread('20230504.xlsx','sheet1','O4:P5718'); figure; plot(data1(:,1),data1(:,2),'-r',data2(:,1),data2(:,2),'-b',data3(:,1),data3(:,2),'-g',data4(:,1),data4(:,2),'-m',data5(:,1),data5(:,2),'-y',data6(:,1),data6(:,2),'-k',data7(:,1),data7(:,2),'-c',data3(:,1),data3(:,2),'-w'); legend('Data 1','Data 2','Data 3','Data 4','Data 5','Data 6','Data 7','Data 8'); xlabel('X Axis'); ylabel('Y Axis'); title('Data Plot'); [y1,x1] = findpeaks(data1(:,2),data1(:,1)); [y2,x2] = findpeaks(data2(:,2),data2(:,1)); [y3,x3] = findpeaks(data3(:,2),data3(:,1)); [y4,x4] = findpeaks(data4(:,2),data4(:,1));[y5,x5] = findpeaks(data5(:,2),data5(:,1));[y6,x6] = findpeaks(data6(:,2),data6(:,1));[y7,x7] = findpeaks(data7(:,2),data7(:,1));[y8,x8] = findpeaks(data8(:,2),data8(:,1));hold on; plot(x1,y1,'or',x2,y2,'ob'); hold off;
这段代码读取了以.xlsx格式存储的表格数据,并绘制了8条曲线的图像,每条曲线都由两列数据组成。代码中使用了findpeaks函数来查找每条曲线的峰值,并用红色圆点和蓝色圆点标记了前两条曲线的峰值位置。最后的效果图中,横轴为X Axis,纵轴为Y Axis,图像标题为Data Plot,图例中列出了每条曲线对应的数据名称。
num=xlsread( shuju.xlsx );
你好!你的第一个问题是关于 MATLAB 中读取 Excel 文件的函数 `xlsread`。在这个函数中,你可以通过指定文件名和工作表名称来读取 Excel 文件中的数据。
根据你提供的代码,你想要读取名为 "shuju.xlsx" 的 Excel 文件,并将数据存储在变量 `num` 中。是的,你的代码是正确的。但是,在使用 `xlsread` 函数之前,你需要确保将该 Excel 文件放在 MATLAB 当前工作目录中,或者提供完整的文件路径。
另外,需要注意的是,`xlsread` 函数返回的是一个数值矩阵,其中包含了 Excel 文件中指定工作表的数据。如果你也想获取其他信息,比如工作表名称或者基本设置,请参考 MATLAB 的官方文档进行进一步了解。
希望这个回答能够帮到你!如果你有任何其他问题,请随时提问。
