Create a matrix with missing data and remove any column (second dimension) containing two or more missing values. Return the new matrix and the logical row vector that indicates which columns ofAwere removed. A = [NaN NaN 5 3 NaN 5 7 NaN 9 2; 8 9 NaN 1 4 5 6 5 NaN 5; NaN 4...
This will produce a single column matrix with all elements of T where corresponding Flag elements are greater than 2. If you want to organize this into different columns then I would suggest keeping the first for loop you have set up.
