Why is MATLAB so fast in matrix multiplication?
I am making some benchmarks with CUDA, C++, C#, Java, and using MATLAB for verification and matrix generation. When I perform matrix multiplication with MATLAB, 2048×2048 and even bigger matrices are almost instantly multiplied. 1024×1024 2048×2048 4096×4096 ——— ——— ——— CUDA C (ms) 43.11 391.05 3407.99 C++ (ms) 6137.10 64369.29 551390.93 C# (ms) 10509.00 300684.00 … Read more
Is it possible to define more than one function per file in MATLAB, and access them from outside that file?
When I was studying for my undergraduate degree in EE, MATLAB required each function to be defined in its own file, even if it was a one-liner. I’m studying for a graduate degree now, and I have to write a project in MATLAB. Is this still a requirement for newer versions of MATLAB? If it … Read more
xkcd style graphs in MATLAB
So talented people have figured out how to make xkcd style graphs in Mathematica, in LaTeX, in Python and in R already. How can one use MATLAB to produce a plot that looks like the one above? What I have tried I created wiggly lines, but I couldn’t get wiggly axes. The only solution I … Read more
Representing and solving a maze given an image
What is the best way to represent and solve a maze given an image? Given an JPEG image (as seen above), what’s the best way to read it in, parse it into some data structure and solve the maze? My first instinct is to read the image in pixel by pixel and store it in … Read more

How can I index a MATLAB array returned by a function without first assigning it to a local variable?
For example, if I want to read the middle value from magic(5), I can do so like this: M = magic(5); value = M(3,3); to get value == 13. I’d like to be able to do something like one of these: value = magic(5)(3,3); value = (magic(5))(3,3); to dispense with the intermediate variable. However, MATLAB … Read more
Read .mat files in Python
Is it possible to read binary MATLAB .mat files in Python? I’ve seen that SciPy has alleged support for reading .mat files, but I’m unsuccessful with it. I installed SciPy version 0.7.0, and I can’t find the loadmat() method. 12 s 12 An import is required, import scipy.io… import scipy.io mat = scipy.io.loadmat(‘file.mat’)
