import hdf5storage 创建一些数据 data_array = np.array([1, 2, 3, 4, 5]) data_dict = {'field1': [1, 2, 3], 'field2': [4, 5, 6]} 将数据组织成字典 data_to_save = { 'array': data_array, 'dictionary': data_dict } 保存数据为.mat文件 hdf5storage.savemat('saved_data_hdf5...

MATLAB 7.3及以上版本需要使用HDF5的库,scipy不支持该类版本mat文件的读取。 4. 样例 >>> from os.path import dirname, join as pjoin >>> import scipy.io as sio Get the filename for an example .mat file from the tests/data directory. >>> data_dir = pjoin(dirname(sio.__file__), 'mat...
1. pythondict字符串用单引号,json强制规定双引号。2.jsonkey name 必须是字符串, python是hashable,如元组也可以3.json:true false null 对应python的True False None4. pythondictvalue里可以嵌套tuple,json里只有array,json.dumps({1:(1,2)})的结果是{"1":[1,2]}5. python {“me”: “我”} 是合...

For dictionary-based compressors like GZIP and LZF, it’s much more efficient to compress long runs of identical values, like all the zero values collected from the first two bytes of the dataset’s integers. There are also savings from the repeated elements at the third byte position. Only...

使用.attrs向HDF5数据对象添加属性很容易。它有一个dictionary-like语法:h5obj[attr_name] = attr_value。属性值类型可以是整数、字符串、浮点和数组。您可以使用以下两行向数据集添加两个属性: hf['array'].attrs['Last Value'] = ihf['array'].attrs['Time Added'] = ctime(time()) 为了演示,我在代码...
