MATLAB

Comentarios: I would state I've been utilizing MATLAB reliably for around 3 years, since my first year in doctoral level college. In undergrad, I may have utilized it a couple of times for a homework set. I say "I may have" in light of the fact that I don't exactly recollect that anything about it aside from that I had an establishment circle. My involvement in programming before MATLAB was some BASIC from youth and a smidgen of Pascal from a few courses in undergrad. My alumni counsel was an overwhelming MATLAB client, and my underlying knowledge with it included disentangling his MATLAB code for doing a few plots. In the meantime, I was taking a controls course which expected me to learn Simulink.

Puntos a favor: I esteem MATLAB. It is so smart and easy to make programming to do what you require. It has amazing exploring and profiling devices. It is cross stage, making code easy to share (expecting alternate people have forked out for the not by any stretch of the imagination unobtrusive allow). It has interfaces to other programming. In any case, there are a couple of things about it that chafe me. I'd get a kick out of the opportunity to get warning from different people what things aggravate them about MATLAB.

Contras: Supplanting subsref and subsasgn in a class is greatly awkward. The issue is this. Expect you override subsref with the true objective to change lead of obj(...). By then your subsref is moreover required the dialect structure obj.propname. With the objective for it to manage this viably (i.e. carry on the proportional as the intrinsic subsref) it needs to reimplement all of the checks for access confirmations that are normally done by the system. For precisely how precarious this is, see our rep's answer for my request here. Beside this genuine inconvenience, it's furthermore inefficient for each subsref to need to switch on the requesting type ('.', '()', or '{}') on each call, and for the system to need to collect a struct that joins the requesting type and furthermore the rundowns. To the degree I can see, it would be so much better if the various requesting accentuations called three unmistakable procedures.

Comentarios: the benefits with matlab has been very satisfactory because through this software I managed to perform four regression programs: Linear Regression (least squares methods), Nonlinear Regression (Newton and Rhapson, Ascending Steps and Marquart). This program served to present the work of promotion in the university, which consisted in taking the data of a researcher on the behavior of the size of the fish with respect to the time and to estimate the parameters of the mathematical model exponential of Von Bertalaffi to find the mathematical expression that calculates the length of a fish. The program made three functional representations: the analytical, the tabular and the graphical. With this program I was able to manipulate the data, change colors, thicknesses of the lines, place the main title and title to the axes, in addition, the results could be exported to the word processor for the final report. This program has also provided me with tools for teaching calculus with analytical geometry (subject of functions), differential and integral calculus, with the possibility of manipulating the results and visualizing their changes when changes are made in the functional analytical representation. With this strategy the student has a greater possibility to reflect on the representations of the functions and their results. When I had difficulties to perform a complex calculation or use advanced programs I was supported by the documentation included in the help window, where there is a great variety of programming examples and software commands.

Puntos a favor: It is a language of high level of technical computing that facilitates simple and complex numerical calculations, which also allows the graphic visualization in 3D and 2D of them. It has a wide application in scientific studies. Integrates numerical analysis and matrix calculation where problems are expressed in the same way. It has specialized programs called toolboxes highlighting in the area of teaching basic mathematics, financial mathematics, statistics, simulation of dynamic systems, among others. It is an ideal software to develop advanced control systems in the engineering area. Allows the control of fonts, Greek letters, symbols, subscripts and superscripts. Make presentations with animation, with supports of colors as it is desired by the user. It allows you to make impressions both of the created program, the calculation made, of the 2D and 3D graphics, results table. It allows to export and import images, graphs, tables and mathematical expressions. You can enter and extract data from the fmatlab quickly. It has a wide range of linear algebra functions, specialized mathematical functions, logical and arithmetic operators, elementary matrices and vector manipulation, special matrices, basic statistics and data analysis, polynomials and interpolation. It has a help folder for software operation through a manual that allows it to be used by all types of beginner users or not.

Contras: The software despite having a documentation of its commands: description, characteristics and access, it is necessary for the user to understand that to create a program and can be manipulated: change data, formulas, presentation of results, fix badly scheduled lines , you must first execute the tutorm command to save the file where you want it, and then return to the saved file and execute other commands, this process requires a lot of practice and for some users it is complicated, therefore they stop using it. have extensive knowledge of the integrals and their methods to solve.
