Question

I am using simulated annealing optimization toolbox. I have input a vector x and i want to save vector x at each iteration but it will display x value only at final iteration. How to save value of x at each iteration and display at the output.
x=[1 3 4 5 6 7 2 9] save x at each iteration and display x at all iteration.

I have a vector x=[2 3 4 5] and value of x change at each iteration.I want to compare value of x at current iteration with value of x at previous iteration.So how can i store value of x at previous iteration.
eg- for i=1:10 x=[2 3 4 5] x_new=[5 3 2 4]%after some calculation value of x at next iteration compare x with x_new

I have row vector r=[1 2 3 4 5 6 7 8 9 10] and from this i generate another row vector of size 4 that is z=randperm(10,4) now i want to randomly select a single element from remaining element of r.
r=[1 2 3 4 5 6 7 8 9 10]; z=randperm(10,4);

Question

I have a row vector x which is random permutation of r where r=1:15 .I want to make a program in which whenever value of r is equal to x increase the counter else counter contain previous value.
first check the which element of array is equal to r and the if is equal then increment the count by one.
