Hi,
I want to know the diiference in the attacehd image, ass well i would like to know how to convert [] to '' the strcamp will work well.
groupName = [11,12];
a = num2cell(groupName)
c = {'42', '12'}
rows = strcmp(a,c)
thanks,

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
