Save a column as a variable

Hi! This is the code I have so far:

c=zeros(271,4);
for k=150:420;%
c(k-149,1)=k;%i
c(k-149,2)=sum(LENG2*10==k);%
c(k-149,3)=sum(LENG2*10==k)/4.1937

I was wondering if there is a way to store this

c(k-149,3)=sum(LENG2*10==k)/4.1937

as a single variable? Thank you!

Lili.

Hi Lili,

If I understand correctly, you fill the matrix c with data inside the 'for' loop and now you want to extract/copy the third column of c into another variable.

Colon operator can be used for this purpose. If A is a given matrix, A(:,n) is the nth column of matrix A.

In your case, the third column can be stored inside variable 'var' ( 271x1 double vector ) on completion of the 'for' loop

var = c(:,3)
