This creates a 1x4 cell array

Array = [0, 1,3,0];
A = num2cell(Array);
C = cellfun(@num2str,A,'UniformOutput',false)
C = 1x4 cell array
    {'0'}    {'1'}    {'3'}    {'0'}

Rather than creating a cell array containing char vectors, why not create a string array?

x = [0 1 3 0];
s = string(x)
s = 1×4 string array
    "0"    "1"    "3"    "0"
three = s(3)
three = "3"
threeChar = s{3}
threeChar = '3'
whos
  Name           Size            Bytes  Class     Attributes

  s              1x4               312  string              
  three          1x1               150  string              
  threeChar      1x1                 2  char                
  x              1x4                32  double              

I'm not 100% sure that indexing with curly braces to create a char vector was supported in release R2018b but if it wasn't calling char on the string array would work.
