Problem 32. Most nonzero elements in row

function r = fullest_row(a)
x=sum(a==0);
y=max(x);
row=0;

for i=1:length(x)
     if x(i)==y
     row=i;
end
r=row;
end

whats wrong with the code???

[Azzi Abdelmalek]

Give a short example: a= ... and what should be the result?

Probably this line

 x=sum(a==0);

should really be this

 x=sum(any(a),2);

The whole thing looks like it could be done in 1 line

[~,row]=max( sum(any(a),2) );

[ricardo gunawan]

thx that help alot anyway the code i modified a little

 [~,row]=max( sum(a~=0,2) );

where do you learn and pratice matlab? i want to learn it fully

Answer 2

[Azzi Abdelmalek]

I don't know what should be the result r, but I can see that the value of r is erased each loop

r=rows

maybe you can initialize r

r=[]

then write

r(end+1)=rows
