if a= -1 0 2 -3 5 -10
and b= 2 -3 5 0 4 1
are two corresponding arrays . how to sort values of (b) in an increasing order with keeping its corresponding values in array (a).
the answer should be like this:
a= 0 -3 -10 -1 5 2
b= -3 0 1 2 4 5

Have a look at the documentation for sort. You can do it as follows:
[b,idx]=sort(b)
a=a(idx)
