If I am trying to write a "while" loop for while the bottom row of a matrix has only one non-zero value, what would I write after the "while" to specify only that condition?

Lets say I have a matrix of:

zeros(6,7)

And I want to run a function only as long as there is one non-zero element in the 6th row. How would I do that until a second non-zero element is placed there?

Try this while m is your matrix:

while nnz(m(end, :)) == 1
    % Do something
end
