Code to read/write NumPy .NPY files in MATLAB
>> a = rand(5,4,3); >> writeNPY(a, 'a.npy'); >> b = readNPY('a.npy'); >> sum(a(:)==b(:)) ans = 60
See test_readNPY.m for matlab reading/writing tests.
Note re: memory mapping npy files
See exampleMemmap.m for example of how to memory map a npy file in matlab, which is not trivial when the file uses C-ordering (i.e. row-major order) rather than fortran-ordering (i.e. column-major ordering). Matlab's memory mapping only supports fortran, but Python's default is C so npy files created with Python defaults are not straightforward to read in Matlab.
