I found difficulties with the Problem 25 on Cody here is my solution:

function B = remove_nan_rows(A)
[x,y]=size(A)
[row, col] = find(isnan(A))
B=[];
for i=1:x
    if (i ~=row) 
        B=[B ;A(i,:)]
    end
end

for A=1:10, the algorithm didn't work, can someone help me with figuring out what's wrong.

Thanks in advance!

Consider that isnan(A) returns a logical array, and that any() can work along a specified direction.

B = A(~any(isnan(A),2),:);

or something like that.

@DGM Can you please rewite you answer on another comment so I can accept it as an answer!

Okay.

B = A(~any(isnan(A),2),:);

or something like that.
