hi, i receive this error...How can i solve it?
arr = struct with fields:
bb: {76x1 cell}
disp(arr.bb)
{'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Mini' } {'On Mini' } {'On Mini' } {'On Mini' } {'On Mini' } {'On Mini' } {'On Mini' } {'On Mini' } {'On Mini' } {'On Mini' } {'On Mini' } {'On Mini' } {'On Mini' } {'On Mini' } {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'} {'On Micro'}
cell2mat(arr.bb)
Error using cat

Error in cell2mat (line 83)

thank ..good explanation

@Luca Re see the FAQ for a good explanation of a cell array:
It explains how and when to use curly braces, square bracket, or round parentheses. I think it will help you get a good intuitive feel for when to use each.

Hi,
Assuming you are triying to convert cell array of characters into string array.
You can use "string" function for your case as shown below.
stringMatrix = string(arr.bb)
