MATLAB: How can i make a single column matrix

basiccolumn matrixmatrix array

function [v] = int_col(n)
v = rand([n;-1;1]);
end
in command window
int_col(6)
Error using rand
Size vector should be a row vector with real elements.
Error in int_col (line 2)
v = rand([n;-1;1]);
i have no idea whats wrong in this program
i want to create a column matrix of column n values must be less than n and greater than 1

Although the original question does not give the basic random number specifications (particularly the number type and if repetitions are allowed or not), perhaps randperm does what you need:
>> randperm(5)'
ans =
   1
   4
   5
   3
   2
