select a specific element of each matrix in a string

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?

One way to go about it would be as below:

tmp = [U{1,:}];      % Places all the data from the cell array into a 448*448 matrix.
Solution = tmp(1,:); % Gets the first element of each U.
clear tmp

Hope that helps!

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

thank you very much. Now, I have 2 matrix of 1*448 I want to plot them as U for X axis and K as Y axis how can I do that?
