Try this:

A = [1 nan 3 nan;
  1 5 6 0;
  2 2 3 4;
  2 5 6 0;
  2 6 7 8;
  3 1 2 3;
  4 1 2 3]

badColumns = isnan(A(1,:)) % Find cols with nan in top row.
fixedA = A(:,~badColumns) % Get all except the bad columns.

Whichever answer worked best for you (they're both valid), you should accept. (and you should have commented on instead of creating a new answer)
