![]() Looks like you're also missing a -liconv or similar to link GNU libiconv?Ĭompiling Octave on a Mac can be tricky. Are you sure you have a good OpenBLAS build and it's on the path? Or are you trying to compile against Apple Accelerate as your BLAS/LAPACK implementation? ![]() Thank you and have a good day ahead!Ĭgejsv and zgejsv are LAPACK functions, which should be included in your BLAS. I would welcome any guidance or advice on how to resolve this issue and proceed further. To compile Octave I use the GNU toolchain from MacPorts: g++ (MacPorts gcc10 10.2.0_5) 10.2.0.

I obtained the source code from a GitHub repository: :gnu-octave/octave.git. I would like to compile GNU Octave from source code on a macOS BigSur 11.2.2. If you need help, you can easily get it from different platforms and get in touch with professionals in MATLAB for help.On 3/9/21 3:53 AM, Maxim Abalenkov wrote: Many professors and scientists use it to solve complex problems, and its community is huge. Schools and colleges use it to teach their students. Your priority should be MATLAB because there are more users compared to Octave. If you can afford MATLAB, then buy it, or if your school or college provides it, then use it otherwise, use Octave, which is not very different from MATLAB. Their syntax is also different from each other, so you won’t be able to run code from one software to another. These toolboxes will make your projects easier to make and analyze. MATLAB runs smoother than Octave and offers various toolboxes to use in your projects like the image processing toolbox and robotics toolbox etc. But MATLAB has a lot more functionality than Octave like it has Simulink, which is used to develop and analyze control systems and power systems. You can say Octave is a free version of MATLAB with almost the same syntax as MATLAB. ![]() There are some differences in MATLAB and Octave, but mostly they are the same. In this tutorial, we will discuss the difference between MATLAB and Octave.
