Proficiency in NumPy brings the data scientist one step closer to unlocking Python’s full potential for comprehensive data analytics. Those who are transitioning from academic research will find Python’s NumPy library to be a natural transition point because of its similarity to the MATLAB programming language. Ultimately, every aspiring data scientist should be familiar with the variety of tools available to them. In MATLAB, the default element data type is a double float, which is important when performing element-by-element division. In Python, the element type of an array is decided when the array is defined.In Python, slicing is left inclusive and right exclusive, whereas in MATLAB slicing is inclusive at both ends.In Python, indexing starts at 0 and is performed with brackets, whereas in MATLAB indexing begins at 1 and is performed with parentheses.Defining an array in Python requires passing the NumPy function a list, whereas in MATLAB, defining a vector is very flexible and does not require commas.Both languages support vectorization and easy element-by-element operations - care needs to be taken with MATLAB as the default operations are often matrix operations.Here are some examples of equivalent code in both languages: The biggest challenge could very well be learning the syntactic differences between the languages. Proficient MATLAB users should find NumPy to be quite intuitive, as the NumPy array functions very similarly to MATLAB’s cell array data structure. NumPy provides the basic “array” data structure, which forms the backbone of multidimensional matrices and high-level data science packages, including pandas and scikit-learn. Such interfaces allow nearly all of MATLAB’s functionality to be reproduced in Python.Īll MATLAB users should become well-acquainted with NumPy, an essential Python library. Because Python does not include a user interface, data scientists need to utilize a third-party user interface. It is an open source, general programming language with countless libraries that aid in data analysis and manipulation. Python is often a data scientist’s first choice for data analysis. With this in mind, it is important for academics transitioning into professional data science to broaden their skill set to include free and open source tool kits. The source code is hidden from the user and any programs written with MATLAB can solely be used by MATLAB license holders. MATLAB’s main drawbacks, when it comes to analysis, stem from its proprietary nature. MATLAB’s other strengths include its deep library of functions and extensive documentation, a virtual “instruction manual” full of detailed explanations and examples. Of course, the true power of MATLAB can only be unleashed through more deliberate and verbose programming, but users can gradually move into this more complicated space as they become more comfortable with programming. Because of this, MATLAB is a great entrance point for scientists into programmatic analysis. It is possible to import, model, and visualize structured data without typing a single line of code. This means new users can quickly get up and running with their data without knowing how to code. MathWorks has put a great deal of effort into making MATLAB’s user interface both expansive and intuitive. Perhaps most important is its low barrier of entry for users with little programming experience. MATLAB has several benefits when it comes to data analysis. This post aims to compare the functionalities of MATLAB with Python’s NumPy library, in order to assist those transitioning from academic research into a career in data science. Luckily, for experienced MATLAB users, the transition to free and open source tools, such as Python’s NumPy, is fairly straight-forward. It is simply too expensive for most companies to be able to afford a license. However, due to its high cost, MATLAB is not very common beyond the academy. This technical article was written for The Data Incubator by Dan Taylor, a Fellow of our 2017 Spring cohort in Washington, DC.įor many of us with roots in academic research, MATLAB was our first introduction to data analysis. In addition to their feedback we wanted to develop a data-driven approach for determining what we should be teaching in our data science corporate training and our free fellowship for masters and PhDs looking to enter data science careers in industry. Much of our curriculum is based on feedback from corporate and government partners about the technologies they are using and learning. At The Data Incubator, we pride ourselves on having the most up to date data science curriculum available.
