Hi I'm trying understand why the following notification of an error appears on the command window ">> fillMissingData Index exceeds matrix dimensions.
Error in fillMissingData (line 17) tday=varargin(1);" but I can not . Can Somebody show what is wrong with this function
function my_prices=fillMissingData(prices, varargin)
% my_prices=fillMissingData(prices) fills missing price with previous
% day's price
% my_prices=fillMissingData(prices, tday, cday) fills missing prices with previous day's price including non-trading days
% as specified in cday
if (nargin == 1)
my_prices=prices;
for t=2:size(my_prices, 1)
missData=~isfinite(my_prices(t, :, :));
my_prices(t, missData)=my_prices(t-1, missData);
end
else
% We deal only with 2 dim prices array here.
tday=varargin(1);
cday=varargin(2);
my_prices=NaN*zeros(size(cday, 1), size(prices, 2));
tdayIdx=find(tday==cday(1));
if (~isempty(tdayIdx))
my_prices(1, :)=prices(tdayIdx, :);
end
for t=2:size(my_prices, 1)
tdayIdx=find(tday==cday(t));
if (~isempty(tdayIdx))
my_prices(t, :)=prices(tdayIdx, :);
missData=find(~isfinite(my_prices(t, :)));
my_prices(t, missData)=my_prices(t-1, missData);
else
my_prices(t, :)=my_prices(t-1, :);
end
end
end

I imagine you meant to do
tday=varargin{1};
cday=varargin{2};
