How to get struct results in a loop?
显示 更早的评论
I have a function that reads a number of files with the extension .m and turns them into inline functions in a struct. The purpose of the function is that the user can load as many models as he wants and the program will always respond with the correct number of entries.
filePattern = fullfile(myFolder, 'model_*.m'); % Only files with prefix and suffix defined in this project
theFiles = dir(filePattern);
FnCarbona = struct; %Creates a structure that will receive function pointers in files
for k = 1 : length(theFiles) % This is from another post here in Matlab Answer
baseFileName = theFiles(k).name;
fullFileName = fullfile(theFiles(k).folder, baseFileName);
fprintf(1, 'Lendo o modelo .... %s\n', fullFileName);
newStr = regexprep(baseFileName,'.m','');
FnCarbona(k).ponteiro= str2func(newStr);
FnCarbona(k).nome = newStr;
end
[n, m]= size(FnCarbona);
This part works pretty well. If I run individually, I get the vectors correctly (5 vector 1x50 elements)
The problem is when I try to access this in a (for) loop.
data=zeros(m,50);
for i= 1: m
data(i)= FnCarbona(i).ponteiro();
end
Then I get the error message: Unable to perform assignment because the left and right sides have a different number of elements.
Could someone help me? I want

Note that rather than creating an entirely new structure array FnCarbona (and expanding it on each loop iteration), you can simply use the already-existing theFiles structure array.

data(i,:) = FnCarbona(i).ponteiro();
% ^^ indexing needs to specify what happens to all 50 elements.
