setenv('AWS_ACCESS_KEY_ID', YOUR_AWS_ACCESS_KEY_ID);
setenv('AWS_SECRET_ACCESS_KEY', YOUR_AWS_SECRET_ACCESS_KEY);

在 MATLAB Online 中打开

Once you have your environment set up, you should be able to treat files on S3 as you would treat any local file, e.g.,

rawdataPath = 's3://companya/Frontier/FieldData/file.csv.gz'
localDir = 'C:\Downloads';
% copy .gz to local directory:
copyfile(rawdataPath,localDir)
% or unzip .gz to local directory:
gunzip(rawdataPath,localDir)
