Creating a variable to from data in a matrix

I have loaded a text file and it is currently set as a variable, input1, in matrix form. I need a vector that is equal to the variables in this matrix of the first column from the 3rd row to the last row of the column.

Correct me if i am wrong but I believe to create a vector of the entire column can be done like this:

x = input1(:,1);

Is there a similar way to code this to only take the values starting at the third row?

Right now I have created column vectors consisting of the colums in the matrix. Then I wrote this but it does not seem to work either.

x = column1(3,:)

I have also transposed this and it still is not seeming to work. I am unsure what to do and would appreciate any help!

Thank you

Hi,

you can select the first column starting from the third row doing this:

selection = matrix(3:end,1);
