Hi,
I am trying to access value of a cell
>> a={'1,65,4,5'}
a =
1×1 cell array
{'1,65,4,5'}
>> a(2)
Index exceeds the number of array elements (1).
>> a{2}
Index exceeds array bounds.
Thanks
Jinang

Hi Stephen,
expected output - number 65. The problem is that I have data from a file which has a={'1,65,4,5'}, I understand removing the quotes will solve it but I cant change the file that generates the data. It is a single cell, is there a way to convert it to 1x4 array?

Edited because of the comments:
a = {'1,65,4,5'}
b = str2num(a{:})
b(2)
