This is made easy with the datetime function (introduced in R2014b) and following the documentation to Generate Sequence of Dates and Time. 

% MATLAB 2019a
t1 = datetime(1982,1,1);
t2 = datetime(2015,12,1);
t = t1:t2;
t = t(:);      % Force column

Alternatively, you can specify the number of linearly-spaced points between two dates using the linspace command. 

t_alt = linspace(t1,t2,480).';

You can convert to the y-M-d format you specified with datetime as well.

t_format = datetime(t,'Format','y-M-d')
