Problem 7. Column Removal

All solutions with score 11 or 12 use the regexp cheat.

Is there somewhere to go to receive advice on how to improve your code?

i can't think of a better solution having size less than 19!

why isn't B = (A(:,n)=[]); working? thanks

How to improvise this code?

It's very MATLAB!

this was actually not that difficult :)

a good way to learn

There should be a single-column input matrix in the test suite.

This was fun! Not difficult, but kind of challenging!

A(n,:)=[]; B = A; it works,but I'm wrong,who tell me the reason?

Better test cases could be provided for edge cases.

Great problem.
Lets you dug deep into the documentation for an awesome solution.

Good problem

good

Good one

Why this is not working?
B = A ( : , ~=n)
I know logic operator needs something~=n but I cannot decide how to correct it? Also, I can write if statement in a for loop but its size is huge.

good

function B = column_removal(A,n)
A(:,n) = [];
B = A;
end

Can someone please tell me what is wrong with this code?
