But numpy is like the original MATLAB, where compiled whole-array methods are much faster. I am running a Matlab script in jupyter notebook after importing matlab.engine as bellow: for i 1 : size (myarr,1). In MATLAB you can get away with lots of iterations, since it does jit compilations.

While arange steps by 1s, the actual values are float, hence the indexing error.Īnd a variable, array, cannot be created by this assignment: In : x2=1Ĭorrect ways of creating such an array/list in Python: In : x2 = np.zeros(6)īut your f loop just puts the same value in all slots for f = 1:tsįor that we really should use whole-array methods: In : x2 = np.full(6,fill_value=2.3) After installing the package python-matlab-bridge and pyzmq, I try to use the pymatbridge by the Usage instruction: Python 2.7.6 (default, Nov 10 2013, 19:24:24) MSC v.1500 64 bit (AMD64) on win3. You don't get the error in the actual loop, because the 1:ts iteration actually creates integers in the range: > 1:ts If I try to index it with the last value, ts, I get the same sort of error: > f=tsĮrror: x2(6.66667): subscripts must be either integers 1 to (2^63)-1 or logicals Initially x2 is undefined, but is created when we start the f loop: > x2Įrror: 'x2' undefined near line 1 column 1 Regarding the TypeError: list indices must be integers or slices, not numpy.float64 Blaha, Senior Systems Engineer, Raytheon Integrated Defense Systems mlab is a repackaging effort to make things up-to-date. Thanks for your terrific work on this very-useful Python tool George A.
Unable to resolve the name py. Mlabwrap is a high-level python to Matlab bridge that lets Matlab look like a normal python library. Tips to determine if an error originates in Python or MATLAB code. How can I fix this? what changes can I make in the x2(f) = x1(end) because whatever I do it shows different error every time. Determine if Error is Python or MATLAB Error. import matlab.engine eng () eng.eval('x 4 ') Synta圎rror: Error: The expression to the left of the equals sign is not a valid target for an assignment. from scipy.io import loadmat data loadmat ('C:\Users\Sakraan\Desktop\stomachpain.mat') but I get the following error: data loadmat ('C:\Users\Sakraan\Desktop\stomachpain.mat') Synta圎rror: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape.

This is Python code I came up with import numpy as np It shows Synta圎rror: cannot assign to function call Im using Ubuntu 12.04, Matlab version 2013 and python 2.7.3.
T = 100 % for the time period user wants to see the mirage So I have installed pymatbridge but I was unable to make it successfully. % all of the given time are in milisecond
