Save a dictionary of names and arrays into a matlab style mat file.
Mat file python data.
Reading mat files into python python notebook using data from cross position activity recognition 17 279.
V4 level 1 0 v6 and v7 to 7 2 matfiles are supported.
Coming from the academia the annotations for the dataset was in the mat format.
It should be composed of simple data types like dict list str int and float.
Reading matlab structures in mat files does not seem supported at this point.

Explore and run machine learning code with kaggle notebooks using data from cross position activity recognition.
Dictionary with variable names as keys and loaded matrices as values.
Reading them in is definitely the easy part.
If you want to inspect the contents of a matlab file without reading the data into memory use the whosmat command.
The matlab variables matrices arrays can be stored in mat files in order to read this data in python you would need a scipy io package.
Mat scipy io loadmat file mat similarly you can use savemat to export to mat files.
Beginning at release 7 3 of matlab mat files are actually saved using the hdf5 format by default except if you use the vx flag at save time see in matlab.
These files can be read in python using for instance the pytables or h5py package.

Matlab structs are a little bit like python dicts except the field names must be strings.
Reading them in is definitely the easy part.
Any matlab object can be a value of a.
Because scipy does not supply one we do not implement the hdf5 7 3 interface here.
