I have an 300x2 array in which I need to find a certain numbert in colum 1, e.g. 10. Once the number is found I need to extract the corresponding value in colum 2.

idx = A(:, 1) == 10; % find the index that 1st column = 10
b = A(idx, 2); % extract the corresponding data in 2nd column
Or in one line
b = A(A(:,1)==10, 2);
