How to Save multiple results into one array

This seems simple, but I can't wrap my head around it

I am trying to save 2 variables that are output from the mink, where k=2, function into a single array

the results should be consecutive and be in a horizontal array, such that - for the first iteration the output was 4 and 6 and the second iteration the outputs are 8 and 9

so the array should be xval = [4,6,7,8..]

Below is the code I was working with however it did not work, any help is appreciated

xvalue=zeros(2*length(x),1);
for i=1:length(x)
xvalue(i)=mink(abs(Lx-x(i)),2); %

end

Answer 1

[Stephen23]

n = numel(x);
xvalue = zeros(2,n);
for ii = 1:n
    xvalue(:,ii) = mink(abs(Lx-x(ii)),2);
end
xvalue = xvalue(:).'

Answer 2

[madhan ravi]

xvalue = cell(numel(x),1);
for ii = 1:numel(x)
    xvalue(ii) = mink(abs(Lx-x(ii)),2); 
end
celldisp(xvalue)
cat(2,xvalue{:})

thanks for the input, madhan

I get an error that I have pasted below, could you break down this process - also is there a method that circumvents the use of cells

Conversion to cell from double is not possible.

Error in load_point_charges (line 65)
    xvalue(ii) = mink(abs(Lx-x(ii)),2);

xvalue{ii} % had to use {}
