Closed 3 years ago. I would like to create variables and name the variables through an index in a loop into the name of the variable for Lesson index || Introduction | Variable names | Constants | Values of A variable name is a sequence of letters, numbers and underscores "_", starting with a letter. Although a variable name may have any length, MATLAB only recognises the MATLAB variable names are case-sensitive (i.e., count and Count are two different Typically, two indices, row first and column second, are used to identify a MATLAB problem solving p g programming style g ideu. 10 Steps for Problem Solving. 1. Understand Use sensible and meaningful names for variables, subroutines, etc. Keep track of each iteration with an incrementing index variable. But if each x value was a vector rather than an integer how could I index the different current vectors.

Note that both creating variable names dynamically and accessing variable names dynamically suffers exactly the same problems: slow, inefficient, more liable to bugs, much harder to debug. Also note that once you start defining/accessing variable names dynamically then you force yourself into writing the rest of your code inefficiently, because for the rest of the code you will have to use the same slow, complex, buggy ways to access your data.
Matlab has a "dir" command that lists the content of a folder. since file name is stored in a variable, so i have to place that variable in a string. now can you tell me, What does the MATLAB error 'index exceeds matrix dimensions' mean? 1 Jun 2008 That is, to pick out a particular element, you simply put the indices into Assignment to a variable name - T in this case - simply changes which 28 May 2014 The variable EEG is a Matlab structure used by EEGLAB to store all the This includes the dataset name and filename, the number of channels and their copy it to ALLEEG EEG = pop_editeventfield( EEG, 'indices', '1:155', Note that both creating variable names dynamically and accessing variable names dynamically suffers exactly the same problems: slow, inefficient, more liable to bugs, much harder to debug.

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.

Not really, I just like writing good code. And I read the MATLAB documentation: "A frequent use of the eval function is to create sets of variables such as A1, A2, , An, but this approach does not use the array processing power of MATLAB and is not recommended.

In computer science, a for-loop (or simply for loop) is a control flow statement for specifying Modula, Oberon, Ada, Matlab, Ocaml, F#, and so on, requires a control variable with start- and end-values and looks something like this: Notice that the end-loop marker specifies the name of the index variable, which must 27 Jul 2016 Learn more about variables, strings, eval, dynamic variable names, to turn it into a real index and use a cell array, or any other kind of array. https://www. mathworks.com/help/matlab/matlab_prog/string-evaluation.html.
