Add a constant to just one column

I am trying to add 1900 to entries in my first column of a matrix to make them a more accurate date. 89 42 49 55 72 63 68 77 82 76 67 90 45 50 56 59 62 68 75 77 75 66 91 44 43 60 60 60 65 69 74 70 70.

I am reading in this matrix but want it changed to 1989 42 49 55 72 63 68 77 82 76 67 1990 45 50 56 59 62 68 75 77 75 66 1991 44 43 60 60 60 65 69 74 70 70

Dear Dakota Bateman

i haven`t understand your question completely but i think you want too add some constant value to first column of your matrix;

let

   a = randi(5,5,5);
      Result = [(a(:,1)+2),a(:,(2:end))]; % here i am adding 2 to my first column

i hope it will help you.

If your array/matrix is x

x(:,1)=x(:,1)+1900;
