I want to convert cell 'A' to a matrix 'B'.
A=
columns 1 through 10
{1x1 cell} {1x1 cell} {1x1 cell} {1x1 cell}...
columns 1 through 20
{1x1 cell} {1x1 cell} {1x1 cell} {1x1 cell}...
I want to have a 'B' as:
B =
1 2 3 4 5 6 7 8 9 ... 20
I tried B(1)=cell2mat(A{1}), but can I avoid doing it one by one?
Thanks!

As usual it would be helpful if you post the input data in valid Matlab syntax, such that we can try our suggestion by copy&paste them. Currently it is not clear what the "{1x1 cell}" contains. Looking at your comments it seems, like these are cell strings.

B = [A{:}];
B = [B{:}];

Are the contents strings?
If so, throw in a:
B = cellfun(@str2double,B);
B = [B{:}]

The expressions converting a "row cell of cells" to the corresponding "row vector" are
B = [ A{ : } ]
C = [ B{ : } ]
The expression for converting a 2-D cell of cells to the corresponding 2-D matrix is
C = repmat(cell2mat( [ A{:} ] ),size(A))

is there a way to make this work for a cell array containing cell arrays of different sizes?

Maybe so:
a = strings(1,length(A)) % or a = zeros(1,length(A)), if A is an integerarray
for i = 1:length(A)
a(1,i) = (convertCharsToStrings(A{i})) %if A is a Stringarray
end
