I have a problem related to my following code... Code generation required variable 'B1' to be fully defined before sub scripting it.

function B1 = SortSignificanceFirst(B)

[mB, ~] = size(B);
SI = zeros(mB,2);
for b=1:mB
    [mBB, ~] = size(B(b,1));
    SI(b,:) = [mBB b];
end
SI_Sorted = sortrows(SI);
for b=1:mB
    B1(b,1) = B(SI_Sorted(mB-b+1,2),1);
end

Just pre-declare B1 as

B1 = zeros(mB,1);

[hemasai proddutur]

before b1 or in the loop?

[Walter Roberson]

Before the loop that assigns into B1.
