Problem 60736. Conditional transpose II

Though this function is considered slower for larger matrices, but since we are only dealing with vectors here, I assume it is good. Though I will run some tests to see how good it actually is.

Of course, the best function to employ here is the one that just changes the header/flag of the array and not the data stored in the array.

Though I was unable to find how to utilize it here.
And I wonder how the Leading solution will fare against vectors with a big number of elements.
