Hi everyone,
I have two cells of strings: A(a,1) and B(b,1), where a>b.
I want to add B in A at a certain position, where there are already c blank rows (c<b).
I tried it with "replace", obtaining the following error:
"Replacement text must be either scalar or the same size as the match text."
Any suggestion?
Thank you :)

the elements of B are not inserted in A because the code stops before

It would be better if you show us a small example code with data.

Hi Francesca,
I understand that you are currently facing a challenge involving the addition of a cell array 'B' into specific positions within 'A,' where there are existing 'C' blank rows.
The error message you've encountered suggests that the replacement text provided during the "replace" operation may not align in size with the matched text.
To address this error, a solution would involve splitting the cell array 'A' into two parts
  • The substring before the positions of the blank rows.
  • The substring after the positions of the blank rows.
Following this split, you can concatenate the string preceding the blank, the contents of cell array 'B,' and the string following the blank. Finally, assign this updated array back to 'A.'
I have assumed that you already know the index of the blank rows in 'A.' However, if you're uncertain about these indices, you can find them using the following code:
blank_positions = find(cellfun('isempty', A));
For more detailed information about the functions mentioned above, you can refer to the following documentations:
Hope this helps.
