where dynamicExpression is a variable or expression that, when evaluated, returns a character vector or, starting in R2017b, a string scalar. Field names that you reference with expressions are called dynamic fieldnames, or sometimes dynamic field names. For example, create a field name from the current date:
How to create a loop to reference each different structure; Can I dynanically reference a variable name, similar to dynamic field references; Does isfield return with false when the field does exist in a structure; How to selectively extract information from a matrix/MAT file in MATLAB 8.1 (R2013a) How to extract a specific data value from a ...
26.02.2017 · I have a 1-by-1 struct that possesses 3 fields named B, C, and D. Is there any way to call D by its index (i.e., D is the third field of struct A, so call the third field of struct A without mentioning the field name D) rather than its name (i.e, A.D)?
How to use structure variable names in for loop; Does comma-separated assignment to a structure not work when the structure is indexed in MATLAB 7.8 (R2009a) How to set missing fields in a structure array to default values stored in another structure array (with same field names) Get a field value from all elements of a structure
If you need to use a structure what I found worked very well was to first convert to a cell then you have the best of both worlds. S = struct('A', [1 2], 'B',[3 4 5]); S_Cell = struct2cell(S); %Then as per gnovice for loopIndex = 1:numel(S_Sell) % Loop over the number of cells array = S{loopIndex}; % Access the contents of each cell %# Do stuff with array end
I have a structure with many fields which are vectors of different lengths. I would like to access the fields within a loop, in order. I tried getfield as follows but MATLAB doesn't like that. How ...

13.12.2005 · 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 contents using curly braces {} , and structures (known in MATLAB as the type struct ) where …
As I have complex parameter structure (for the Cplex MATLAB interface), and wish to be able to enter user selected parameters into it. Any ideas appreciated! I ...

Field names that you reference with expressions are called dynamic fieldnames, or sometimes dynamic field names.. For example, create a field name from the current date:
Then in my function I have created other variables which have certain values. I want to create fieldnames in the previous structure with the name of these ...
Dynamically determine a structure field name at run time from a variable ... Field names that you reference with expressions are called dynamic fieldnames, ...
When you use the getfield function, you can access a field of the structure returned by a function without using a temporary variable to hold that structure ...
struct2cell creates shared-data-copies of the field variables. So, while there is overhead involved in creating the variable header info, the data itself is not ...
