Easy but my solution might not be optimal

good basic problem

good Problem!

great

Still new to matlab and I didn't realise that you can add elements in a vector, at least I am learning new things

Hardest one yet

I like this task

It's easy when you're turning it into a column vector

idk

good

How can the leading solution size be 7?

good idea

ddd

one of the simplest task.

who can tell me what is this????/!!

Ha! Small tricks.

你好骚啊

Come on, this one is so easy

I am using either for loop or sum command (twice) but it saying error. Any clue?

lets go

I used the "sum" function to solve this problem really quickly.

Why doesn't it work?
function y=vecsum(x)
y=symsum(x(i),i,1,size(x));
end

Because you are doing it wrong!
You should check the basis of 'sum' topic in the help.
Here you go: https://www.mathworks.com/help/matlab/ref/sum.html?searchHighlight=sum%20vector&s_tid=doc_srchtitle

very easy

nice

easy

good job

Nice!

This user appears to have gamed the system, with fraudulent "likes" of this unremarkable solution submitted by 'sock-puppet' accounts. —DIV

easy :)

can anyone please help me to find out the where is the mistake, i am a new learner .........

You have to define a function vecsum() like:

function y = vecsum(x)
y=0;
for x= 0:1:10
y=x+y;
end
end

because your answer is executed by calling function in test suite below. The function's name is decided by problem creater.

What is your code Sir?
If you write your code here, I can say where is the mistake.

This solution works.

unable to find the sum of all numbers in input vector, so the test set is correct. I make my solution: ' function y = vecsum(x) y = sum(x); end ' smaller?

Thanks

Yay! I got it right! Omg I'm so happy!

What does this solution mean. In other words, can someone explain the solution step-by-step.

Good question!

The "y=" is missing from "y=sum(x)".

@Mr. Tim . Atleast You give me positive reply.Thanks a lot.Can I further talk to you regarding MATLAB CODY Guidence..

Sure, ok.

Bien Javier

y = sum(x)
x=[1 2 3 5]

is not that true, i am confused.

You haven't stated the *Function* name, input values and output values. Without them the code from the site cannot check your code.

Secondly you've declared X after you wanted to run a function with it.

The program will read:

Sum of X equals Y. X equals Zero or Not a Number, therefore Y is Zero or Not a Number. Next line, X is [Array]. Okay, X is [Array].

Also good practice to end your functions with a semicolon ;

Next line, X is [Array]. Okay, X is [Array]. Y is still 0 or NaN. Also good practice to end your functions with a semicolon ;

This solution is just for a laugh - the test suite is pretty weak!

good job

thanks

you're welcome

I agree with HaveF.

Not to mention that it doesn't even run

WOCAO!!!!!!!!!! this is a trcik..........

there is definitely something wrong with cody.I am getting 'Undefined function 'cody.verifyCode' for input arguments of type 'char'.' for my solution

Why isn't nansum(x) a solution?

Test for vactor
x = [1 4;3 4]
It will add columns only.

Problem is finding the sum of all numbers in an input vector, so the test set is correct.
