Dear Friends,
Could you tell me how to write for and while loops with restricted variable input with steps in function?
For instance;
-2<=x<=2
step:0.1
f(x)=((x^3+9)+(x^2-4))/(x*7+5))
so how can I write it to run properly and to make plot?

x = -2:0.1:2;
f = ( x.^3 + 9 + x.^2 - 4 ) ./ ( x*7 + 5 );
figure; plot( x, f )
You don't need loops at all. Matlab is built for vectorisation.
