can we use 'and' condition in "for"

can we use 'and' condition in "for" like example _ for re1=1000 && rh=200. _

You can't, it is always

 for loopIndex = someArray
    ...
 end

which is not condition-based. You can do it with WHILE statements though..

 re1 = 0 ;
 rh  = 0 ;
 while re1 < 0.5 && rh > -1
    ...
    re1 = rand(1) ;
    rh  = randn(1) ;
 end

You can also use break and continue in either loop statement, but we usually don't use them in the context that you describe. It is more for situations as follows

 for k = 1 : maxRetry
    ...
    found = ...
    if found
       break ;
    end
 end

can we use if condition inside the while loop

[Cedric]

You can use IF statements inside both loops, yes. As mentioned, the difference between these two loops is that one is based on a loop index which takes iteratively all values of a 1D array (or all columns of a 2D array), and the other on a loop condition. Other than that, you can do whatever you want inside both statements, and even nest them.
