the matlab code and the output i was expecting (gauss elimination method) my code in python: the output i got: Answer Your problem is related to casting. Without info, numpy cast your matrix to integer numbers, so when you divide, the result is not a float. For example 2 / 6 = 0 and not 0.33333. If you put yo…

Matlab to Python – Why is nested forloop running twice as often in python?
I need z to be the same index value in Python as in MATLAB, which I think means 991 in Matlab = 990 in Python. The original MATLAB code (z = 991) My Python code (z = 1980) Why is my z double the amount? Where is my error? Thanks! Answer Your last line (test_timer1 += 1) needs to be
how to build app container in Python or Matlab
I have just started learning Python. I would like to build an application with bar menus and different windows contained inside what I think coders call a ‘boiler plate’ a window containing everything. The app has to contain also pull-down menus with file handling, settings, functions .. some are …
How to detect if a data frame has nan values in MATLAB?
I am new to Matlab and Python. Currently i am working on some assignment where i want to check if data frame has nan values in matlab or not ? Hoping to hear back soon with response. Thank You !! Answer In Python with Pandas you can use below code:
What is the matplotlib equivalent of MATLAB Figure.Position?
I am working on converting some MATLAB plotting code to Python / matplotlib. The original MATLAB code contains this: I am trying to determine the matplotlib equivalent of the assignment to F.Position. MATLAB docs describe this property as conveying the location and size of the drawable area, but matplotlib.fi…
How to sample data points for two variables that has highest (close to +1) or lowest (close to zero) correlation coefficient?
Let’s assume that we have N (N=212 in this case) number of datapoints for both variables A and B. I have to sample n (n=50 in this case) number of data points for A and B such that A and B should have the highest possible positive correlation coefficient or lowest correlation coefficient (close to zero)…
MATLAB Engine API for Python. Error: MATLAB Engine for Python supports Python version
I’m working on my Master’s Thesis. My director uses MATLAB, I use Python. So I need to run his MATLAB scripts on Python. There are many questions out there on this topic. I tried to install Install MATLAB Engine API for Python (https://es.mathworks.com/help/matlab/matlab_external/install-the-matla…
Saving Numpy array using scipy.io.savemat MATLAB does not produce the necessary .mat file
I have written a function to convert a NumPy array into a mat file using scipy.io.savemat() but it produces a generic type of file: File with the same name but not of type .mat as expected. The array I want to save is of type <class ‘numpy.ndarray’> as verified by the print statement. I don&…
Vectorizing Tensor Products from Python to Matlab
I am in the process of converting some code from Python into Matlab. I have code working that produces the same results, but I am wondering if there may be a way to vectorize some of my for loops in the Matlab code as it take a long time to run. X in an Nxd matrix, diff is an NxNxd
MATLAB freqz2 equivalent in Python
I’m trying to find a Python library that works equivalently to MATLAB’s freqz2 for image processing, since scipy.signal.freqz only seems to work for 1-D arrays. Answer Found an amazing library for plotting the 3D surface of the 2-D FFT called plotly. I leave here the lines of code I used to emulat…
