MATLAB: Alternative to using EVAL. dynamic function names eval. Hi All, I need to call a function whose name is decided dynamically at runtime. Is there an alternative to using the eval function? My requirement is this: I have a Matlab application with a non-linear optimisation model as the core solver for this application. I need the user to have the option to plug and play different models. This works, but the Matlab debugger warns that the variables in the above LoadModelPkgCall string are unused. Is there an alternative to using the eval function? Thanks for the help.

MATLAB: Alternative to using 'eval' in order to evaluate string. Ask Question Asked 1 year, 8 months ago. Active 1 year, 8 months ago. Viewed 295 times 2. I have a bunch of char arrays within a cell array that actually represents the declaration of MATLAB structs. Something like this: tmp{1} = 'testData.input = [1;2;3;4;5]' tmp{2} = 'testData.output = [2;4;6;8;10]' I need to execute these. To allow the MATLAB parser to perform stricter checks on your code and avoid untrapped errors and other unexpected behaviors, do not include output arguments in the input to the eval function. For example, the statement eval(['output = ',expression]) is not recommended. Instead, specify output arguments to the eval function to store the results of the evaluated expression In my opinion, you have two options: use the parser you already have, matlab, which you invoke as you have done with eval. However, you have to abide by the rules of this parser, so the size of whatever you combine must be the same Quicker alternative to EVAL.

Another alternative of Matlab is Maxima which was inspired by the legendary Algebra system Macsyma. It is a system used for manipulating numerical expressions such as Taylor series, Laplace transformations, Vectors, Tensors, and Matrices. Very accurate results are provided by using exact floating numbers, fractional values, and integers First, here is Mathwork's list of alternatives to eval. You could also be clever and use eval() in a compiled application to build your mCode interpreter, but the Matlab compiler doesn't allow that for obvious reasons. share | improve this answer | follow | answered Nov 11 '13 at 15:37. supyo supyo. 2,929 2 2 gold badges 17 17 silver badges 35 35 bronze badges +1 for the Mathworks link.

MATLAB: Alternative to using 'eval' in order to evaluate

MATLAB's eval function poses the same kind of problem for the Compiler's dependency analysis that callbacks do: the Compiler cannot examine text strings to determine if they contain function calls.

Note. In most cases, using the eval function is less efficient than using other MATLAB functions and language constructs, and the resulting code can be more difficult to read and debug. For more information, see Alternatives to the eval Function eval() Parameters. The eval() function takes three parameters:. expression - the string parsed and evaluated as a Python expression; globals (optional) - a dictionary; locals (optional)- a mapping object. Dictionary is the standard and commonly used mapping type in Python. The use of globals and locals will be discussed later in this article Merci pour l'alternative au eval, parc contre je n'arrive pas à trouver ce que signifie la première ligne avec la commande repmat.

Un test est une alternative entre deux commandes (ou groupe de commandes) Matlab sélectionnées suivant le résultat d'une opération logique. Le résultat d'une expression logique est une variable logique ou booléenne qui vaut 1 pour VRAIet 0pour FAUX. Dans Matlab on dispose du classique if-elseagrémenté du elseifparfois bien utile Use dynamic field references, the notation .(), where possible, instead of setfield, getfield, and eval. History In MATLAB 6.5 (Release 13), we introduced dynamic field references into MATLAB. What are they and why should you use them? In MATLAB, there are 3 basic types of arrays, traditional ones where you index using parentheses (), cell arrays where you can address the content de même : eval(['cd ' + int2str(i)]), sera avantageusement remplacé par cd(int2str(i)). si j'ai bien compris, il y a un certain nombre de fichiers, nommés, par exemple '1' à '17', dans divers dossiers. Dans l'ensemble des dossiers, il y a un unique fichier de chaque nom mais la répartition par dossier est inconnue a priori. Il n'y a pas. Matlab - sprintf ----- Bonjour Voici mon code Matlab: x01 = 5.56; x02=8.65; x=03 =..... et ainsi de suite for n= 1:10 x = sprintf('x%02d',n);.... end ici je dis que x correspond tout d'abord à x01, puis x02, puis x03... jusqu'à x10. Mon souci c'est que x est considéré comme une suite de caractères ici (un mot en gros). Or ce que j'aimerais faire, c'est donner à x la valeur qui est. Now, if you still really want to create variables with dynamically generated names, you need to use eval. With eval, you use MATLAB commands to generate the string that will perform the operation you intend. For example, eval ('A=10') has the same effect as A=10, and eval(['A' 'B' '=10']) has the same effect as AB=10, only the eval method executes much more slowly. So in a loop, you could use.

that of Matlab, Octave, FreeMat, and Scilab. In summary, we conclude that Octave is the best viable alternative to Matlab because it was not only fully compatible (in terms of syntax) with Matlab in our tests, but it also performed very well. 1 Introduction 1.1 Overvie Variable Names Valid Names. A valid variable name starts with a letter, followed by letters, digits, or underscores. MATLAB ® is case sensitive, so A and a are not the same variable. The maximum length of a variable name is the value that the namelengthmax command returns.. You cannot define variables with the same names as MATLAB keywords, such as if or end..
