Problem 6. Select every other element of a vector

Not clear.

What does it mean? It is not clear

It's not understandable.

This problem is definitely not clear.

Select the first, the third, the fifth, the seventh, ... element.

nice problem

I cant understand this problem.

nice

All solutions with score 10 or 11 use the regexp cheat.

very good one

Yes, you should change the redaction of the problem,maybe

function y = everyOther(x)
for i=1:length(x)
if mod(x(i),2)~=0
y(i)=x(i)
end
end
y=y(y>0)

end

What's wrong with this solution?

y = x(mod(x,2)==1);
it's not working, and i cant see why

nice problem

nice

good

I can't understand, why is this wrong?
j=1;
for i=1:length(x)
if rem(x(i),2)~=0
y(j)=x(i);
j=j+1;
end
end

Nice problem, but I have been doing this with my son and it would be good if the exercises were more gently graduated with relevant syntax so he can learn without relying on his dad knowing Matlab!

I can't believe someone solved this with size 9.

The leading solution is not a solution. It just makes all the test assertions true.

Indexing is one of more important things in matlab and matrices. Gotta learn them good before heading on.

Helo, hey hey ey

Test suite suggests solution !

nice

the example made confusion

cool!

nice!

cool!

hard

I overcomplicated this one at first, but once you figure it out, it's not too bad

Absolutely mind boggling

this one's pretty good

I have a question is that :test6 and test7 is the column vector,but test1-5 is the row vector,
so if test 1-5 are passed ,the test 6 and 7 are not passed

这个问题出的有点问题，没有规范化

OMG, It wasn't about finding the odd numbers?

Below is my code but it is failing the test 6 and 7. I tried inputting x=randi(100,10,1) and x=primes(20) in the scratchpad and the code works fine, outputing the right answer. There seems to be a problem with the evaluation of the answers.

function y = everyOther(x)
y = [];
for i = 1:2:length(x);
y(end+1) = x(i);
end
