The matrix is like this: Data =
1 2 NaN 4 NaN
4 NaN 2 NaN 2
7 1 5 NaN 4
9 4 3 7 NaN
row 1 = 2 NaNs, row 2 = 2 NaNs, row 3 = 1 NaN, row 4 = 1 NaN.
and it can be described like this: [2 2 1 1] what can i do if i want to make it like this:
Data =
7 1 5 NaN 4
9 4 3 7 NaN
1 2 NaN 4 NaN
4 NaN 2 NaN 2
row 1 = 1 NaN, row 2 = 1 NaN, row 3 = 2 NaNs, row 4 = 2 NaNs. and it can be described like this: [1 1 2 2]
what to do? thanks before :)

[ii ii] = sort(sum(isnan(Data),2))
out = Data(ii,:)
