Dear friends,

I would like to know whether there is a difference between following cases. Your responses are appreciated.

`Case 1X = 1;Y = X + 4;Z = X + Y;Case 2X = 1; Y = X + 4; Z = X + Y;`

Other cases that I want to compare are as follows:

`Case 3v1 = k1{t};nVar = size(v1, 2);CP = randsample(nVar-1, 2);Case 4CP = randsample(size(k1{t}, 2)-1, 2);`
