Demo遍历输出路径下所有.csv文件的路径

clear all;
close all;
clc;
foldPath = 'F:\yourfoldname';
searchFoldStr = strcat(foldPath,'\*.csv');
dirStruc = dir(searchFoldStr);
dirCell = struct2cell(dirStruc);
fileTotal = size(dirCell,1);
for fileIndex = 1:fileTotal
    filepath = cell2mat(strcat(foldPath,dirCell(1,fileIndex)));
% or filepath = strcat(foldpath,cell2mat(dirCell(1,fileIndex)));
    disp filepath;
end

Another method

foldPath = 'F:\yourfoldname';  % fold path
searchFoldStr = strcat(foldPath,'\*.csv');
dirStruc = dir(searchFoldStr);
for fileIndex = 1:fileTotal
    filepath = strcat(foldPath,dirStruc(fileIndex).name);
    disp filepath;
end
