selecting the random element by having distance to others

This code generates random number

index = randperm(length(1:200),5);

I want to control this generator. Each number have a distance to each others

for example

index=[117   121    15    14   187]

117 and 121 is near to each other also 14 amd 15. This example is not acceptable.

200 divided by 5 equals 40.

First element should be between 1 to 40

Second elemnet should be between 41 to 80

Third elemnet should be between 81 to 120

4th ---> 121 to 160

5th ---> 161 to 200

If the fist element is 39 the second one should not be 42. 39 and 42 is close to each other.

something like this result

index=[2   53    90    140   199]

I have no idea what you are talking about by reading your example. Please explain further.

If you want your random numbers to be distributed like this, the randperm is not the correct function. You can use randi() and shift them to your required range.

x = randi([1 40], 1, 5) + (0:40:160);

Result

>> x
x =
    27    42   114   158   188
