Problem 2. Make the vector [1 2 3 4 5 6 7 8 9 10]

use colon notation

Nice

good

good problem

good problem.

GOOD

it's magic ^_^

easy

Well crafted problem!

super

great problem

you are sooo right

Easy way to learn concatenation :)

easy

very easy

How come?

linspace gives you a smaller size :)

is it ok

Great problem

wow very fun!

[1:1:10]

why not

Nice. What is the difference between this vector and x = linspace(1,10,10)?

Hello Matthew Jones,
Linspace is similar to the colon operator ":", but gives direct control over the number of points.
In x = linspace(1,10,10) you directly enter the number of points and the function generates equally spaced vector but when you use ":" operator, you need to mention step size.

.

good job

i really don't get why it is wrong lol

try again you are so best

This really saves time!

im also wondering why ' x=1:10' doesn't work

no,it works
try it without using ' ' (x = 1:10;)

Nice!

I have tried multiple things that would create that vector, and it won't accept my answer. I am not sure what this question wants from me I guess.

The output of your function is x, not x_correct, so remove "_correct" and it should work.

remove the square brackets,size will reduce even more

why isnt the [] notation required for the solving of the puzzle?

how do you improve on this solution?

Shorter than mine.

ermmm why not? It works when I type it in...

Please help!!!!not sure where i went wrong

You just need to type x=[1,2,3,4...10] or x=1:10

Just edit that line in the code. Not the whole thing

You should name the function exatly 'oneToTen',and apparently,your x is from 1 to 9,not 1 to 10.

x=1:10 do the same.

I do not deem that these problems can enhance one's performance.....

This question could have been a bit more challenging.

why is this incorrect?

You need to insert "function x=oneToTen" as the first line of your function.

give a value of y simple calling the function oneToTen. it will definitely work

I do not understand the point of Cody... I cannot use "eval 1:10;" but I can use "str2num 1:10;" which is overhead + eval 1:10... Please make Cody evaluate the functions used in submitted code

what's the "str2num" mean?

str2num means "convert string to number"; even more cryptic is the fact that "str2num 1:10" is equivalent to "str2num('1:10')" (Matlab allows you to omit the single quotes and parentheses when using functions that take character strings as arguments).

If I were to type this in to MATLAB right now, it absolutely would create the desired vector. I don't think I understand Cody.

Cody requires you to define a function, so you have to precede this statement by an appropriate function statement.

please unlock the solution

The metric used to evaluate the performance of a solution is http://www.mathworks.com/matlabcentral/fileexchange/34754-calculate-size

As you can see if you inspect the code, it has nothing to do with speed or memory. That is why I proposed this solution, in order to show that you can become the leader with a code that is not efficient at all, either in execution speed or in memory use. Although I think the idea of Cody is great and challenging I believe that the metric that is used nowadays should be rethought.

interesting

Cannot be reproduced, creates an error in execution in R2016a.

cumsum(ones(1,10))
