if folderExists == 7 disp('文件夹存在。'); else disp('文件夹不存在。'); end 整合以上步骤,完整的MATLAB脚本示例如下: matlab % 假设我们要检查的文件夹在当前工作目录下,名为'myFolder' folderPath = fullfile(pwd, 'myFolder'); % 使用exist函数检查文件夹是否存在
1. folder是相对路径: folder = './abc/'; if ~exist(folder,'dir') mkdir(folder) end 在当前文件夹(存放所运行的matlab代码的文件夹)中判断是否存在文件夹abc,如果不存在,则创建。 2. folder是绝对路径: folder = 'D:\qcc\HDmap_statistics_opendrive\python_code\33782107\paramPolyhhhh\'; if ~exist...

mkdir('D:\matlab\work\myfolder') ``` 需要注意的是,指定的路径必须存在,并且要具有创建文件夹的权限。如果文件夹已经存在,将会抛出一个警告信息。如果要避免警告信息并且只在文件夹不存在时创建文件夹,可以使用exist函数进行判断,例如: ```matlab if ~exist('myfolder', 'dir') mkdir('myfolder'); end ...
mkdir folderName creates the folder folderName. If folderName exists, MATLAB® issues a warning. If the operation is not successful, mkdir throws an error to the Command Window. example mkdir parentFolder folderName creates folderName in parentFolder. If parentFolder does not exist, MATLAB atte...
