The usual way to iterate through a struct data type in MATLAB is using the fieldnames () function as done in: mystruct = struct ('a',3,'b',5,'c',9); fields = fieldnames (mystruct); for i=1:numel (fields) mystruct. (fields {i}); end. Unfortunately, this always generates cell data types, and I would like to use this kind of iteration for a Matlab ...
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 ...
Jul 26, 2019 · As mentioned in the comments above, it is not a good idea to define dynamic variable names. But if you want to avoid manually writing each field name, you can use the fieldnames as shown below. fn=fieldnames (structure); %loop through the fields. for i=1: numel (fn) fn1=fieldnames (structure. (fn {i}))
Note that instead of looping over a number, you can also loop over fields directly, making use of a neat Matlab features that lets you loop through any array. The iteration variable takes on the value of each column of the array. teststruct = struct ('a',3,'b',5,'c',9) fields = fieldnames (teststruct) for fn=fields' fn %# since fn is a 1-by-1 ...

Aug 09, 2019 · pointN : struct. Basically a structure containing point coordinates, what I wish to do is basically fetch the data of the structure in a loop. Unfortunately I wasnt able to achieve this. What I created was. for i = 1:N. varName = strcat ('mystruct.point',int2str (i)); %fetch data using the varname. end.
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
17.02.2019 · For Loops with Struct and Fields. My data is in a structure/filed format B {x}.F {x}.signals.values, The structures and fields are consistant ,Struct B {x} where x =1:inf, F {x} and signals are the same for every iteration of B {x}. However the values are of diffrent sizes and i need to vertically cancatenate to be able to plot the values in on ...
25.07.2019 · Looping through different fields in struct. Learn more about for loop, struct MATLAB. Skip to ... x.s2, x.s3, etc. should be x.s(1), x.s(2), x.s(3), This way it's trivial to access a field, you just use standard matlab indexing. I agree that a table may be more suitable for your data. it would probably be a table with 4 variables (s ...
Sep 21, 2011 · Is it possible to iterate through a MATLAB structure numerically like a vector instead of using the field names? Simply, I am trying to do the following inside an EML block for Simulink: S.a.type...
Feb 28, 2017 · I am using the following code: names = fieldnames (data); % extract names of features. for i = 1:5. class (i) = data.names {i}; end. where data is a struct, and names obviously contains the fieldnames. What I basically want to do is to extract certain field from data, and put them into an array. How can this be done (my attribution in the ...
