how can i make a single column matrix

7 views (last 30 days)
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?

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
