How do you use values from an array as serial numbers to extract values from a different array?

If I am using an array to record values such as [0:10:100], then how can I create a column vector containing values extracted from a table(with two columns, one of which is the independent variable and the other is the dependent variable) with the intervals 0, 10, 20,...,100?

It is not possible to reference ‘row 0’ since MATLAB subscripts begin at 1.
I am not certain what you want, so see if this short example works for you:
T1 = array2table(randi(100, 35, 2)); % Create Random Table
T2ext = T1([1 10:10:30],:); % Extract Rows
.

yi = interp1(x, y, vfit)
Out = [vfit, yi]
That will likely produce the result you want, even though I still have no idea what that is. Note that for this to work, both ‘x’ and ‘vfit’ must be monmotonically either increasing or decreasing, and both must go in the same direction.
