Appending entire Rows in a struct

Hi, I am trying to append an row (of variable size) of a an array inside of a struct. The first line would convert the numerical array into a string array.

The rows in the array vary from 1 to 7 and I want them to display side by side like this so that they can easily be transfered to an excel spreadsheet where all the values would be in one cell

A.k = [1, 2, 3];

A.k = string(A.k);

[1, 2 , 3] -> [ '1, 2, 3']

Biggest issue is knowing how many columns there are and in the case that there's only 1 column that it still works.

Saar - have you considered using num2str?

A.k = [1, 2, 3];
A.k = num2str(A.k);

I mean same difference but my issue is with combing in the index values

[Walter Roberson]

mat2str(A.k) maybe?

Or is the point that your original values are a column (so multiple rows) but you want them side by side? If so, then

mat2str(A.k(:).')

No honestly I think I'm just gonna have to run a loop

You may need to provide a more complex example.

Maybe you have a non-scalar struct??

I do not seem to be catching what you are asking...
