Adding a string value to an array.

13 views (last 30 days)
Given an array of zeros like so....
0 0 0 0
0 0 0 0
0 0 0 0
Using something like
if something = true
A(2,2) = ("x");
end
Is there a function which will use the str(x) and transform the element in the array at (2,2) to this string?

Not really. Arrays are homogenous, the entire array consists of elements of the same class.
As an alternative you could do one of these:
  • use a container array (e.g. cell array, but this will make processing numeric data more complex and less efficient)
  • use a special value (e.g. NaN, -1)
  • store the character value (but this might be easily confused with valid numeric data)
  • store a separate logical mask and/or string/char array.

Hi,
CellArrays would be the right structure to store string data. You can assign values to cell array as follows.
A = cell(4,4);
A{2,2} = 'x';
Hope this helps
