How to save variables from output of function as vector?

function [ A, B] = GetText(filename)
fid = fopen(filename,'r');
x = textscan(fid,'%n%s','headerlines',1);
fclose(fid);
A = x(:,1);
B = x(:,2);
B{1}
A{1}
end
when I use this function
>> [A,B] = GetText(filename)
the output is A and B are cells. I need to use A and B for input to other functions so how do I make A and B save as vectors in the workspace?
thank you

Perhaps like this:
function [A, B] = GetText(filename)
fid = fopen(filename, 'r');
x = textscan(fid,'%n%s','headerlines',1);
fclose(fid);
A = x{1, 1};
B = x{1, 2}; % Typo, was x{2,2}
end
But perhaps "A and B save as vectors" might mean something else. Please post the contents of the variables, or the file, or explain what you expect as output exactly.

Please do not only mention that there is an error, but post the complete error message. There was a typo in my code. Perhaps this caused the error. But most of all: please answer the questions for clarifications. This is your problem and I want to help you, but to do this, it is required to know, what the code is reading and what you want as output. Ignoring questions for clarifications is not useful, if you want others to help you.

I tried this and got A saved as a double (YAY) but B is still saved as a cell. Do you know to fix this?

@Simone Frauenfelder: you specified the second textscan formatSpec to be %s, which according to the documentation "Read as a cell array of character vectors." The variable B is a cell array of character vectors. How do you imagine that character vectors should be, if not in a cell array?
