I don't understand. You can't have characters and numbers in the same column vector. Please give an example.

example: linlist=horzcat(Branch,num2cell(JJ));
JJ is a matrix that includes numbers and Branch is a cell that includes characters(in this case, R and P). i put them together using horzscat and made linlist cell.

So, if I understood you right you have A of size Mx2 where the first column has either the character R or P and the second column has a number. You want to have two other variables One named R and another Named P which they contain the corresponding numbers from the second column of A?
If that's what you want here is a sample code:
A={'R',1; ...
'P',5; ...
'R',3; ...
'R',10; ...
'P',6; ...
'R',8};
R=cell2mat(A(strcmpi(A(:,1),'R'),2))
R =
1
3
10
8
P=cell2mat(A(strcmpi(A(:,1),'P'),2))
P =
5
6

i just want to make a string with the format P(number) or R(number)., in which the numbers belong to second column. i know that i can use strcat but i don't know how to put the numbers in second column in the parenthesis.

figured it out, thank you tho for your answer. i meant below:
out1=cell2mat(A);
out=strcat(A(:,1),'(',(num2str(out1(:,2))),')');
