The variable a is a cell array containing 2 scalar numbers, while b contains 2 CHAR vectors.

a = {42, 12}
a = 1×2 cell array
    {[42]}    {[12]}
c = {'42', '12'}
c = 1×2 cell array
    {'42'}    {'12'}

The square brackets are shown in the command window only an converting them to quotes is not meaningful.

There are many ways to compare the two cell arrays:

a1 = [a{:}];
c1 = str2double(c)
c1 = 1×2
    42    12
a1 == c1
ans = 1×2 logical array
   1   1

or

a2 = sprintfc('%d', [a{:}])
a2 = 1×2 cell array
    {'42'}    {'12'}
strcmp(a2, c)
ans = 1×2 logical array
   1   1
