I currently have a structure array defined in the code as:

C.a = "something";
C.b = 1;
% useful comment
C.c = [ 1.3, 2.0, 3.1];

I would like to create a text file that would contain the values so that i can compile the code and change the struct without recompilation. What is the easiest way to do this? ( I read about readstruct but that requires creating an xml file which is an overkill)

What is fixed? What is flexibel? Does the struct contain 3 fields in all cases?

The number of fields is fixed. The values on the right hand side of the equal sign can change but always within the same type (column vector will be column vector, double will be double, string will be string etc.

在 MATLAB Online 中打开

To save the data in the structure C in a file...

save('savedata.mat', 'C');

To retrieve the data as a structure C later...

load('savedata.mat');

I'm assuming here that the key issue is storing the data in a file and retrieving the data later in the same format. Of course, a .mat file is not a text file.
