%% (Internal) Reshape the input into a column vector
% This function is useful when a function returns a row vector or matrix
% and you want to immediately reshape it in a functional way. Suppose
% f(a,b,c) returns a row vector, matlab will not let you write f(a,b,c)(:)
% - you would have to first store the result. With this function you can
% write colvec(f(a,b,c)) and be assured that the result is a column vector.
%
% x = colvec(x)
%
% Arguments:
%
% + x: data
%
% Output:
%
% + x: columnized data
%
% Example:
%
% See also rowvec
