What can MATLAB do that R cannot do? [closed]

Answer 1

With the sqldf package, R is capable of not only statistics, but serious data mining as well - assuming there is enough RAM on your machine.

And with the RServe package R becomes a regular TCP/IP server; so you can call R out of java (or any other language if you have the api). There is also a package in R to call java out or R.

Answer 2

As a user of both MATLAB and R, I think they are very different applications. I myself have a background in computer science, etc. and I can't help thinking that R is by statisticians for statisticians whereas MATLAB is by programmers for programmers.

R makes it very easy to visualize and compute all sorts of statistical stuff but I wouldn't use it to implement anything signal processing related if it was up to me.

To sum up, if you want to do statistics, use R. If you want to program, use MATLAB or some programming language.

Answer 3

I agree with many of the answers given above. Since the answer is specific to the diffset of MATLAB and R capabilities, I will mention a very important one: MATLAB includes a JVM and has flawless and robust interoperability with Java. All of Java's vast universe of libraries is accessible to the MATLAB user. The MATLAB IDE can be almost be used as a poor man's Eclipse. In comparison, rJava is very immature, despite the very valuable effort of its creator (Roman Francois).

Answer 4

In my experience moving from MATLAB to Python is an easier transition - Python with numpy/scipy is closer to MATLAB in terms of style and features than R. There are also open source direct MATLAB clones Octave and Scilab.

There is certainly much that MATLAB can do that R can't - in my area MATLAB is used a lot for real time data aquisition - most hardware companies include MATLAB interfaces. While this may be possible with R I imagine it would be a lot more involved. Also Simulink provides a whole area of functionality which I think is missing from R. I'm sure there is more but I'm not so familiar with R.

Answer 5

Short answer: no, of course not. While any set of mathematical software packages will have their overlaps, they will always have biases towards certain problem domains. These biases figure strongly in whether or not you want to use one of these packages.

An example of what MATLAB can do that R cannot is interface to real-time hardware for signal processing/acquisition and control. A Simulink model in MATLAB can be configured both to run in simulation on your machine before compiling the code to execute on a real system taking measured data as input and calculating appropriate outputs (what was before a simulation of a control system is now a fully functioning one). With the appropriate hardware board in your machine, you can run real-time control systems through a PC.

R, by contrast, seems firmly set in the role of statistics, where I'm sure it out-performs what MATLAB can do. Similarly, Mathematica is better than MATLAB at symbolic maths; Python is better than MATLAB at general programming; gnuplot is better than all of them at actually creating graphs (er, I assume); and so on.

Answer 6

R is an environment for statistical data analysis and graphics. MATLAB's origins are in numerical computation. The basic language implementations have many features in common if you use them for for data manipulation (e.g., matrix/vector operations).

R has statistical functionality hard to find elsewhere (>2000 Packages on CRAN), and lots of statisticians use it. On the other hand, MATLAB has lots of (expensive) toolboxes for engineering applications like

• image processing/image acquisition,
• filter design,
• fuzzy logic/fuzzy control,
• partial differential equations,
• etc.
