Try this!:D c=n; while n>1 if mod(n,2) n =3*n+1; else n =n/2; end c=[c n]; end

use fix instead of floor or ceil command

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?

use if c==sqrt(a^2 + b^2) flag=true else flag=false

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

Test Suite fails. " Error using evalin. Undefined function or variable 'score'."

This one required a big change in strategy in my case!

function y = nearZero(x) x = [min(x(x~=0)),x,min(x(x~=0))]; index = find(x == 0); y = max([x(index-1),x(index+1)]); end

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?

Use isnan keyword. isnan(NaN) gives 1

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?

Harley Butler submitted a Comment to Solution 1801297

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.

Simillar solutions are really cool and concise.

bentzi grinfeld submitted a Comment to Solution 1799547

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 :')

Why is there "undefined function 'dist' for input arguments of type 'double'."? Works on my machine (and online matlab too)

Paul Smits submitted a Comment to Solution 1788385

Funny that 2017a-style double quotations significantly shorter the size as compared to the 2016b-style string() function alternative :)

I tried solving this in MATLAB & it gave correct answer for the 3rd test suite also

You have mentioned that the input is 4X4 and then you tested on different dimensions. :(

Indeed, My code works until the d = 50 because it's a large number, so our algorithm is correct we should not worry about it, I think we have succeed in this challenge.
