Hi! I have two cells like this:

I assume they are not the same as entering them in the same cell gives me the following error message:

Error using vertcat
Dimensions of arrays being concatenated are not consistent.

How can I transform cell B like cell A so that the text has ''?

For example, cell B should have:

'in B{1,1}: 'from 0738 to 0378'
in B{1,2}: 'from 0933 to 0934'

Notice that in the diagram for A, the entry starts and ends with apostrophe. A is a 1 x 2 cell array, the first entry of which is a character vector.

Notice that in the diagram for B, neither entry has apostrophe, and neither entry has double-quote -- not 'from 0738 to 0738' and not "from 0738 to 0738" . When MATLAB presents text without '' or "" around it, then that text is categorical. So B is 1 x 2 cell, in which the entries are categorical.

However... in R2021b (and current releases) if you have a cell array of categorical values, then the variable browser does not show the contents: instead it would display

| 1 x 1 categorical | 1 x 1 categorical |

So... the output your show cannot happen in the release you have marked as using (R2021b)

Anyhow, try

B = cellstr(string(B));
