I have a code to import an excel file into matlab but I need to import around 250 of these files. Does anyone know how to write a loop for this or is there another way to load them all at one? The code I am using is below.

data = importdata('filename')

textdata = data.textdata;

data = data.data;

t_date = datenum(textdata(:,1),2);

x_date = datenum(textdata(:,3),'mmmyy');

yr = year(x_date);

mth = month(x_date);

for i=1:length(x_date)

calend = calendar(yr(i),mth(i));

if calend(1,1:6) == zeros(1,6)
dy = calend(4,6);
else
dy = calend(3,6);
end

x_date(i) = datenum(yr(i),mth(i),dy);

end

calput = 1.*strcmp(textdata(:,4),'C') + 2.*strcmp(textdata(:,4),'P');
