How to subtract number inside cell

A = {[32,28,30,31],[27,29,30]};
B = {[30,64,72,85],[15,33,62]};
C = cellfun(@minus,A,B,'uni',0)
C = 1×2 cell array
    {[2 -36 -42 -54]}    {[12 -4 -32]}

in my case, the array :

A(2x1 cell)= {[32,28,30,31]} {[27,29,30]}

B(2x1 cell)={[30,64,72,85]}{[[15,33,62]}

It works for me:

A = {[32,28,30,31],[27,29,30]};
B = {[30,64,72,85],[15,33,62]};
C = cellfun(@minus,A,B,'uni',0)
C = 1×2 cell array
    {[2 -36 -42 -54]}    {[12 -4 -32]}

You would get that error if both your description and examples are incorrect, and you actually have nested cell arrays, e.g. in R2021b:

B = {{30,64,72,85},{15,33,62}};
C = cellfun(@minus,A,B,'uni',0)
Error using cellfun
Operator '-' is not supported for operands of type 'cell'.

Or in R2013b (note the error message text change):

>> C = cellfun(@minus,A,B,'uni',0)
Error using cellfun
Undefined function 'minus' for input arguments of type 'cell'.

Try a simple and intuitive for loop:

A = {[32,28,30,31],[27,29,30]}
B = {[30,64,72,85],[15,33,62]}
% A for loop works:
[rows, columns] = size(A)
for col = 1 : columns
	C{col} = A{col} - B{col}
end
% Stephen's method also works, at least in R2021a.
C2 = cellfun(@minus,A,B,'uni',0)

Of course you could also check the dimensions and make sure they're the same before you subtract, and throw up a "friendly" error message if they don't match, rather than barf up a screen of red error messages.
