Sparse norm(S,2) is not available.

Hello i get the error spare norm(S,2) is not available in my code at the line where i have

    Mnrm = 2.5e+5;
    scal = Mnrm/norm(A); % A = 10000x10000 sparse double
    
    % Error using norm
    % Sparse norm(S,2) is not available.

What could be the issue?

Does "normest" instead of "norm" work for your matrix ?

The function norm doesn't support sparse matrix input. You can try full(sqrt(sum(abs(A(:)).^2))) for instead.
