date into double then back to date in loop

I imported dates from an Excel file called original as below:

date =table2array(original(:,1));

datedouble= datenum(date);

I have a for-lop with a for loop variable j such that:

a(j+1,1)= datedouble(j+1,1);

My question: this for loop stores serial number of the date, and I want to conver this back to the dates. I tried datestr(datedouble(j+1,1)), but it says the dimension doesn't matach as it is some sort of 1x10 on the right hand side and left hand side is 1x1.

How can I resolve this?

Thanks!

You should really look at creating a datetime and using its various properties and methods instead of datenum or datestr.

Can you provide a small data set of what you have and what you want?

The issue I am having is a is K by L doubles.

I am running a for-loop in each row, so I store the date.

The issue is I am storing as serial numbers and as in double.

But I want this to change to the actual dates for ease of display when I plot.

So I tried datestr() function to convert back to characters.

When I try to store this into the entry in my for-loop, I get the following error:

Unable to perform assignment because the size of the left

side is 1-by-1 and the size of the right side is 1-by-20.

Help?
