Adding Matrices to struct

Hello

I have this code and it saves the matrices in the struct, but it only saves it in the first column, I want it to save it in both columns as you can see in the picture.

I am also attaching the code

n = 2 ;

M = cell(n, 2) ;

for k = 1 : n

A = [1 2 3; 4 5 6;7 8 9];

M{k} = A ;

end

fields = {'IndivualStiffnessMAtrix','IndivualStiffnessMAtrix2'};

v =cell2struct(M,fields,n)

"but it only saves it in the first column, I want it to save it in both columns as you can see in the picture."

You seem to be confusing the size of a structure with the number of fields that is has: the size of a structure is totally independent of its number of fields.

Your structure actually has size 2x1, as the Variable Viewer clearly states, so it does not have a second column for "both columns" as you wrote. Your structure does have two fields though, which in the Variable Viewer are displayed as two columns, but because these are not columns of the structure your question is really quite unrelated to your example screenshot.

So, how to change it, to have two columns and matrices being saved to both columns of the structure

solution

n = 2 ;
 M = cell(n, 2) ;
 for k = 1 : n
     A = [1 2 3; 4 5 6;7 8 9];
     
    M{k,1} = A ;
    M{k,2} = A ;
    
 end
 fields = {'IndivualStiffnessMAtrix','IndivualStiffnessMAtrix2'};
 v =cell2struct(M,fields,n)

This is saving to both columns of the struct, but the struct is still 2x1 with 2 fields.

You know how to make a 2x2 struct?

[Stephen23]

"You know how to make a 2x2 struct?"

And how many fields should the 2x2 structure have?

Note that the structure in your screenshot does NOT have size 2x2, it has size 2x1 (and has 2 fields). Most likely you are confusing the size of a structure with how its fields are displayed.

here

n = 2 ;
 M = cell(n, 2) ;
 for k = 1 : n
     A = [1 2 3; 4 5 6;7 8 9];
     
    M{k,1} = A ;
    M{k,2} = A ;
    
 end
 fields = {'IndivualStiffnessMAtrix','IndivualStiffnessMAtrix2'};
 v =[cell2struct(M,fields,n) cell2struct(M,fields,n) ]
