It only works for one append!If you append twice, Matlab gives an error "File might be currupt".

scipy.io.savemat('temp.mat',{'data':np.ones(10)})  # write
with open('temp.mat','ab') as f:
    scipy.io.savemat(f, {'newdata1':np.arange(5)})   # append
with open('temp.mat','ab') as f:
   scipy.io.savemat(f, {'newdata2':np.arange(5)})   # append
