Use eval to dynamically save matrices

Im trying to name my matrices in a loop according to a list of algorithms

I would like to have example GC_1 which contains some the matrix rRE

for c=["GC","VC"] % names of my algorithms
    for i=1:2
        for k=1:3 
            A(k,:)=rand(1,6);   
        end  
        A_hat = median(A);  % matrix
        
        temp_var = strcat( c,'_',num2str(i));
        
        eval(sprintf('%s = %g',temp_var,A_hat));
    end
end
% so I would like to have a variable GC_1 containing a matrix as its value.

it works when A_hat is an integer but doesnt work when A_hat is a matrix

% Error: Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax
% error. To construct matrices, use brackets instead of parentheses.

Why don't you write A_hat directly into the eval expression?

eval(sprintf('%s = A_hat',temp_var));

Oh yea it works! Thanks

Please don't number your variables. Instead, learn to use arrays, cell arrays if needed. This will save your next anxious question, which will be: "How can I use my numbered variables, since I have hundreds of them?"

Using arrays properly is the way to write better code. Learn this style of programming, instead of using eval, which will cause you bugs, slow code, and many heartaches.

"Please don't number your variables..."

Indeed. From medieval map charting terra incognito, the warning “Hic Svnt Dracones” is apropos here, too...
