A hybrid MATLAB/C++ programming model for high performance embedded computing is presented. It is shown how the use of a common data model and API can help not only to speed up the development process, but also to keep the original MATLAB model in sync with the evolving C++ code, and thus allowing it to remain a gold standard for the project as it evolves.

We describe the problems associated with the creation of high performance code for mathematical computations. We discuss the advantages and disadvantages of using a high level language like MATLAB and then propose partial evaluation as a way of lessening the disadvantages at little cost. We then go on to describe the design of a partial evaluator for MATLAB and present results showing what perf...

The solution of large, sparse constrained least-squares problems is a staple in scientific and engineering applications. However, currently available codes for such problems are proprietary or based on MATLAB. We announce a freely available C implementation of the fast block pivoting algorithm of Portugal, Judice, and Vicente. Our version is several times faster than Matstoms’ MATLAB implementa...

In this paper a new method for the design of a linear phase distributed amplifier in 180nm CMOS technology is presented. The method is based on analogy between transversal filters and distributed amplifiers topologies. In the proposed method the linearity of the phase at frequency range of 0-50 GHz is obtained by using proper weighting factors for each gain stage in cascaded amplifier topology....

This study has been inspired by the paper "An efficient 3D topology optimization code written in MATLAB” written by Liu and Tovar (2014) demonstrating that SIMP-based three-dimensional (3D) topology optimization of continuum structures can be implemented in 169 lines of MATLAB code. Based on the above paper, we show here that, by simple and easy-to-understand modificati...

We provide a compact 200 line MATLAB code demonstrating how topology optimization (TopOpt) as an inverse design tool may be used in photonics, targeting the of two-dimensional dielectric metalenses and metallic reflector examples. The physics model is solved using finite element method, utilizes MATLAB’s fmincon algorithm to solve problem. In addition presenting itself, we briefly discuss numbe...

Matlab is a popular dynamic array-based language commonly used by students, scientists and engineers who appreciate the interactive development style, the rich set of array operators, the extensive builtin library, and the fact that they do not have to declare static types. Even though these users like to program in Matlab, their computations are often very computeintensive and are better suite...

In sour gas flares,  content like any other components in inlet gas influences adiabatic flame temperature, which, in turn, impacts on the pollutant emission. Wherever flame temperature increases, the endothermic reaction between  and  is accelerated, which means higher  emission to the atmosphere. In this work, we developed an in-house MATLAB code to provide an environment for combustion calcu...

In this paper the Benettin-Wolf algorithm to determine all Lyapunov exponents adapted a class of non-commensurate fractional-order systems modeled by Caputo's derivative and corresponding Matlab code are presented. The continues work started in [Danca & Kuznetsov, 2018], where commensurate is given. To integrate extended system, Adams-Bashforth-Moulton for fractional differential equations util...

In this report, we discuss the implementation and numerical aspects of the Matlab solver sbvp designed for the solution of two-point boundary value problems, which may include a singularity of the first kind, z′(t) = f(t, z(t)) := 1 (t− a) · z(t) + g(t, z(t)) , t ∈ (a, b), R(z(a), z(b)) = 0. The code is based on collocation at either equidistant or Gaussian collocation points. For singular prob...
