how can i make a single column matrix

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

• Do you want floating point values or integer values? It is not clear from the text exactly what output you need: does "values" mean real or integer values?
• Are the values allowed to repeat, or with no repetitions? Or are you just looking for a random permutation?
• What random distribution do you need?

Answer 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
