Hello everyone,

I would like your help in the following :

How can i convert A = [1,2,3,4,5,6……n] to B = [123,456,……n],…….. ???

thanks in advance..!!

One convoluted way of doing this would be to convert to strings and back.

for i = 1:length(A)/3
    B(i) = str2num([num2str(A(3*i-2)),num2str(A(3*i-1)),num2str(A(3*i))]);
end

>> A = [1,2,3];
>> str = sprintf(', %d',A);
>> str = sprintf('(%s)',str(3:end))
str = (1, 2, 3)

I assume your date_num values are datenums?

How about something like:

wd = weekday(date_num + i);
if wd == 1
   i = i + 1;
elseif wd == 7
   i = i + 2;
end
