Load filename loads data from filename.
Scipy load matlab file.
Load data from mat file the function loadmat loads all variables stored in the mat file into a simple python data structure using only python s dict and list objects.
Sometimes it s more convenient to load the matlab structs as python objects rather than numpy structured arrays it can make the access syntax in python a bit more similar to that in matlab.
The documentation page for the loadmat method tells us how it loads matlab structs into numpy structured arrays you can access the members of the structs using the keys.
Here s an example running an octave script via oct2py saving the resulting octave workspace onto a mat file and loading the mat file into python.
Numeric and cell arrays are converted to row ordered nested lists.
Setting this flag to false replicates the behavior of scipy version 0 7 x returning numpy object arrays.
Matstruct fname pjoin data dir teststruct 7 4 glnx86 mat matstruct contents sio loadmat matstruct fname.
V4 level 1 0 v6 and v7 to 7 2 matfiles are supported.
In order to do this use the struct as record false parameter setting to loadmat.
Annots annotations bbox x1 annots annotations fname array dtype uint8 array 00001 jpg dtype u9.
The default setting is true because it allows easier round trip load and save of matlab files.
Arrays are squeezed to eliminate arrays with only one element.
After reading a structure called e g.
You will need an hdf5 python library to read matlab 7 3 format mat files.
Get the filename for an example mat file that contains a matlab struct called teststruct and load the contents.
Matlab up to 7 1 mat files created with matlab up to version 7 1 can be read using the mio module part of scipy io reading structures and arrays of structures is supported elements are accessed with the same syntax as in matlab.
If filename is an ascii file then load filename creates a double precision array containing data from the file.
Because scipy does not supply one we do not implement the hdf5 7 3 interface here.
Whether to load matlab structs as numpy record arrays or as old style numpy arrays with dtype object.
If filename is a mat file then load filename loads variables in the mat file into the matlab workspace.
Try loading the mat file in matlab or octave and saving it again with the v7 option.
