You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: initializeMovie.m
    path of file: ./repos/chebfun/@spinopsphere
    
    the code of the file until where you have to start completion: function [p, opts] = initializeMovie(S, dt, pref, v, compGrid, plotGrid)
%INITIALIZEMOVIE   Initialize a movie when solving a PDE specified by a 
%SPINOPSPHERE.

function [p, opts] = initializeMovie(S, dt, pref, v, compGrid, plotGrid)
%INITIALIZEMOVIE   Initialize a movie when solving a PDE specified by a 
%SPINOPSPHERE.

% Note: P is a NVARSx2 CELL-ARRAY that stores the NVARS plots in the first row
% and the NVARS titles in the second row. OPTS is a 3x1 CELL-ARRAY that stores
% the limits of the colorbar in OPTS{1}, the viewpoint specification in OPTS{2}
% and what kind of data to plot in OPTS{3} (real/imag/abs; when the data is
% complex-valued).

% Set-up:
nVars = S.numVars;                    % Number of variables (>1 for systems)
vscale = max(abs(v(:)));              % Scale of the solution 
dataplot = str2func(pref.dataplot);   % Plot 'abs', 'real' or 'imag'
ll = compGrid{1};                     % Computation grid (lambda-direction)
tt = compGrid{2};                     % Computation grid (theta-direction)
N = 2*(size(ll, 1) - 1);              % Size of computation grid (same in la&th)
lll = plotGrid{1};                    % Movie grid (lambda-direction)
ttt = plotGrid{2};                    % Movie grid (theta-direction)
Nplot = 2*(size(lll, 1) - 1);         % Size of movie grid (same in la&th)
FS = 'fontsize'; fs = 12;             % Fontsize for title

% Viewpoint specification (see SPINPREFSPHERE):
viewSpec = pref.view;
defaultPref = spinprefsphere();
defaultView = defaultPref.view;
while ( length(viewSpec) < 2*nVars )
    viewSpec = [viewSpec, defaultView];
end
