set the vector same length

I have two sets of data, stress and strain. this a project and i have only 5 values in y and 9 values in x axis.

x values (2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016)

and y value (0, 0.05, 0.1, 0.15, 0.2)

I need both vectors to be the same length, which would be [9 X1]. I am not sure what to do . can anyone plese help me? thank you in advance

The approach depends on what you want as the result:

x = [2008,  2009,    2010,   2011,   2012,  2013,  2014,  2015,  2016];
y = [0,  0.05,   0.1,   0.15,  0.2];

y9 = linspace(min(y), max(y), numel(x));                                    % Option #1

y9 = interp1(x(1:numel(y)), y, x, 'linear', 'extrap');                      % Option #2

Try these and see if either of them does what you want.
