Random number from 1 to 100 if the number between 20 to 30 add 100 if the number 50 to 60 minus 100.

Hi guys,

I generated random number 1 to 100.

but i don't know how to change value for 20 to 30 and 50 to 60.

I'll generate 10 samples.

N = 10;
X = randi(100,1,N);

ind = (X >= 20) & (X <= 30);
X(ind) = X(ind) + 100;

ind = (X >= 50) & (X <= 60);
X(ind) = X(ind) - 100;

The only circumstance where what I did may have been a problem is if the first transformation could move a number from the interval [20,30] into the interval [50,60].

But clearly that could never happen under your constraints.
