MATLAB: Select a specific element of each matrix in a string

Question

Hi,

this is my code

K=rand(448);

for i=1:448

g{i}=[0:1:447]';

end

for i=1:448

U{i}=inv(K)*g{i};

end

so U contain 448 element containing 448*1 in each matrix. Now I want to use element(1,1) of each matrix. what should I do?

Answer 1

firstElementOfEachCellOfU = cellfun(@(x)x(1,1),U);
