function a = bullseye(n) a = 1; for i = 2:(n+1)/2 a = padarray(a, [1,1], i, 'both'); end end Why doesn't this function work?

This code is failing the first case of the test suite (instead of [4 8], only [4] is displayed) but passing the rest. I can't find out what is wrong in it! Any suggestions?

Why doesn't the built in function dec2bin() work here?

The test is wrong, the right answer is y_correct = [2 1 3 2];

bad test. to get the test answer you must square the diameter and multiply it by pi, intead of pi*r^2(or pi*d/2^2)

Hi, No mistake in test suit 3, a vector can be a column vector or row vector.

Hi all, I just can't find out why the assertion fails. All works well on my MALTAB but not here. Both codes (commented and not) remove only the words which end with 'ain' and leave the two spaces but still the assertions here has failed.

Thanks for your answer, you had a typo in true, also you should remove ' ' from false and true

The solution which I presented just now works perfectly fine on the live editor of Matlab, but don't know why math works still say it is incorrect?

I experienced the same thing...was able to generate the output exactly but received a failing score. Did you solve your issue?

function y = lengthOnes(x) a = []; idx = [1,find(x=='0') + 1,length(x)+2]; le = length(idx); a(1:le-1) = idx(2:le)-idx(1:le-1)-1; y = max(a); end

You need to specify that the answer must be rounded to 2 decimal places.

You need multiple tests to check a variety of situations.

Since yesterday, I submit the solution ,and it always shows " While evaluating the solution, the server encountered an error caused by temporary unavailability of MATLAB Service. Wait a few minutes for the MATLAB Service to return, and then rescore." I don't know how to deal with it?

Nobody would do this: [ .25; .05; .10; .01; ] If you are going to demonstrate a concept, do it right - minus tricks!

Inconsistent behavior - if you are going to make a question like this, make it representative of what would actual be done and not some arbitrary undocumented rules like "replace a two-word state name with a space"

a = [0 1 0 0; 0 0 1 0]; c = 2; How is the second one the one with the highest money? The first one has $ 0.10 whereas, the second has 0.05. a = [ 0 1 2 1; 0 2 1 1]; c = 1; Here too! How is the first one higher? When you evaluate, you get $ 0.21 for the first one and $ 0.26 for the second.

@Harley, MATLAB functions are case sensitive. Did you try lowercase sum?

I get the correct answers for this, but the website refuses to tell me it is correct. Fix this dumb stuff.

I initially also found that strange. But later I found out the cell structure is different. N by 1 OR 1 by N problem.

why this code is not correct? s = summ(v) >> b=s >> s(1)=[] >> c=[[s],0] >> s=[b+c] >> s(end)=[]

Too many loops and a long solution. But my brain broke down when trying to do it in 4- or 5-dimensional arrays :')
