8/30/2023 0 Comments Matlab vs python online![]() It was created to be a generic language that is easy to read and they. The average time for every operation and language programming is added as a dashed line in the respective color: Python in blue and Matlab in orange. Python is a pretty elegant and intuitive programming language compared to MATLAB. All figures have number of try vs the time used. This data is re-open in Python and plotted using the Maplotlib library. The timing data is exported to *.npz file in Python and to *.mat file in Matlab. The hardware used had the next features: Intel i7 4790k (OC 4.4 Ghz), 24 Gb Ram DDR3 2400 Mhz and Win10. All variables used were double precision floating point (float64) in Python and Matlab. Timing functions were time.time() in Python and “ tic and toc” in Matlab. After that, to see if indexing could be an issue in any of the languages I programmed 2D matrices with 10^3x10^3 elements and 3D matrices with 10^2x10^2x10^2 elements (same quantity of multiplications than in the vector case). The latter allow you to write vector/matrix operations in a way simpler manner while executing Fortran/C code behind the scenes. I used np.random.random() and ‘*’ in Python and rand() and ‘.*’ in Matlab for random initialization and multiplication, respectively. 1 Nasser Fortran is a completely different language (also from the level it operates on) compared to Matlab/Python. I selected a number of 10^6 components as I found it easy to handle but large enough to obtain good average results. I programmed 10 initializations and multiplications in vectors and in 2d/3d matrices. I know Matlab is not updated, but I guess I will not find significant computational optimizations in next versions and I have not any newer version available either. ![]() I used Python 3.6.5 with Numpy 1.14.3 and Matlab R2014b exact version 8.21. I am sure that timings can be improved in both languages with more careful and detailed programming. The main difference between MATLAB and Python is that Python is a general-purpose programming language, while MATLAB is a computing platform that is used. I did not want optimizations or ninja tricks, just threw some fast-programmed lines of code and see which of both languages default method was faster. Python’s powerful preprocessing library has been the source of all kinds of code for nearly a centurypython, boto, and so on. Python is fast and allows you to easily use Python’s classes and methods. So, I began working in a small "benchmark” application programmed by myself to see if that was correct. With Python 1.5 and 2 you use the default Python. I declare myself a “fanboy” of Matlab, and I have always heard that Matlab was really fast for an interpreted language, and it can even beat compiled languages (Idea for another article?). The conception of this article was born some days ago when one of my colleagues said that Python was faster than Matlab in calculations. Before that, I have been using Matlab for many years since I was studying my degree and I also used it extensively during my PhD. Recently, I have had the time and opportunity to begin with Python and machine learning and I love this combination. As an example, Python was already in 2017 the Top Programming Language for IEEE. Python is greatly increasing its popularity lately.
