Scipy Load Matlab File
Setting this flag to false replicates the behavior of scipy version 0 7 x returning numpy object arrays.
Scipy load matlab file. In order to do this use the struct as record false parameter setting to loadmat. Numeric and cell arrays are converted to row ordered nested lists. Struct its lat element can. Here are examples of how to read two variables lat and lon from a mat file called test mat.
Whether to load matlab structs as numpy record arrays or as old style numpy arrays with dtype object. The default setting is true because it allows easier round trip load and save of matlab files. 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. After reading a structure called e g.
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. Annots annotations bbox x1 annots annotations fname array dtype uint8 array 00001 jpg dtype u9. Try loading the mat file in matlab or octave and saving it again with the v7 option. Matstruct fname pjoin data dir teststruct 7 4 glnx86 mat matstruct contents sio loadmat matstruct fname.
Because scipy does not supply one we do not implement the hdf5 7 3 interface here. 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. Python should then open this without problems. 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.
Arrays are squeezed to eliminate arrays with only one element. Get the filename for an example mat file that contains a matlab struct called teststruct and load the contents. V4 level 1 0 v6 and v7 to 7 2 matfiles are supported. You will need an hdf5 python library to read matlab 7 3 format mat files.
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.
