Insert column of strings into numerical matrix

I have a large matrix 44 x 227 (A) and I I am trying to put a string of dates (B) (1 x 44) into column 139 of matrix A.

I figured out how to get the string to stay in date format, but when I try to insert B into matrix A (:,139) it comes out as NaN.

Any help would be appreciated! Thank you!

Cannot put date strings into a matrix of numbers. Convert date strings to numbers (datenum) and insert. If you want the date strings later just pull from matrix and convert (datestr).

Use a table array instead of a matrix.
