Vectorization means that there is no loop over triangles. Vectorized Matlab Codes for Linear Two-Dimensional Elasticityĭirectory of Open Access Journals (Sweden)įull Text Available A vectorized Matlab implementation for the linear finite element is provided for the two-dimensional linear elasticity with mixed boundary conditions. Python also increases the portability and flexibility (interaction with other open source and proprietary software packages) of solutions, and. Matlab and Python have a comparable language philosophy, but Python can offer better performance using its optimizations and parallelization interfaces. In this course we want to introduce Matlab programmers to the usage of Python. Python is becoming a popular language for scientific applications and is increasingly used for high performance computing. Training course 'Porting code from Matlab to Python'ĭiaz, Sandra Klijn, Wouter Deepu, Rajalekshmi Peyser, Alexander Oden, Lena The complete 88 line code is included as an appendix and can be downloaded from the web site of the basic code to include recent PDE-based and black-and-white projection filtering methods. The original code has been extended by a density filter, and a considerable improvemen. It has been developed using the 99 line code presented by Sigmund (Struct Multidisc Optim 21(2):120â€“127, 2001) as a starting point. The paper presents an efficient 88 line MATLAB code for topology optimization. The software implements the encoder and decoder functions, and contains compressed versions of generator and parity-check matrices used in these operations.Įfficient topology optimization in MATLAB using 88 lines of codeĪndreassen, Erik Clausen, Anders Schevenels, Mattias The error-correcting codes implemented are the nine accumulate repeat-4 jagged accumulate (AR4JA) low-density parity-check (LDPC) codes, which have been approved for international standardization by the Consultative Committee for Space Data Systems, and which are scheduled to fly on a series of NASA missions in the Constellation Program.

The software can be used as a single program to simulate the performance of such coded modulation. This software, written separately in C and MATLAB as stand-alone packages with equivalent functionality, implements encoders and decoders for a set of nine error-correcting codes and modulators and demodulators for five modulation types. Matlab code to do multivariate alteration detection (MAD) analysis, maximum autocorrelation factor (MAF) analysis, canonical correlation analysis (CCA) and principal component analysis (PCA) on image data.
