headers are saved in the VariableDescriptions property. Set'PreserveVariableNames'totrueto use the original column headers as table variable names. 示例代码 注意filename改成你的xlsx的名字即可。 filename ="Files_info.xlsx"; opts = detectImportOptions(filename); ...
Read the column headers using the format '%s' four times. Get fileID = fopen(filename); formatSpec = '%s'; N = 4; C_text = textscan(fileID,formatSpec,N,'Delimiter','|'); Read the numeric data in the file. Get C_data0 = textscan(fileID,'%d %f %f %f') C_data0=1×...
