Cody Problem 25. Remove any row in which a NaN appears

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!

In the given case, the row variable comes out to be 1x0 empty double row vector as A doesn't contain any Nan value. So, the condition in the statement

if (i~=row)

is false and thus your assignment is never executed. The Algorithm works as it is written to.

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.

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.
