i need to code matlab for import excel file.

Sure, I can help you with that. Here's an example code that imports an Excel file into MATLAB:

% Specify the file name and sheet name
filename = 'example.xlsx';
sheetname = 'Sheet1';

% Import the data from the Excel file
data = xlsread(filename, sheetname);

% Display the data
disp(data);

In this example, the `xlsread` function is used to read the data from the specified Excel file and sheet. The data is then stored in the `data` variable and displayed using the `disp` function.

Note that you may need to modify the code to match your specific file and sheet names. Let me know if you have any questions!
