Hi everyone. How can I randomly select two values in an array, and then reverse all the values between them? (Including the values selected)

hello

try this

the output has values between 2nd and 5th data flipped

n = 10;
A = (1:n) % array
A = 1×10
     1     2     3     4     5     6     7     8     9    10
ind1 = 2;  % first index
ind2 = 5;  % second index
B = A;
B(ind1:ind2) = B(ind2:-1:ind1)
B = 1×10
     1     5     4     3     2     6     7     8     9    10
