MATLAB: Hi I’m new to Matlab and was trying to plot a graph of 2^n but havn’t been able to.

For example for the range [-5,5]

x = linspace (-5,5,101);
y = 2 .^ x;
plot (x,y);

Mustahsan, what do you mean by restrict? Setting the plotting limits? Something like:

 xlim([pi, 2*pi])

e.g.

a = 1:20;
b = rand(1,20);
b(4:7) = NaN;
newB = interp1( a( ~isnan(b) ), b( ~isnan(b) ), a );

also includes an extrapolation argument that you can read about on the help page:
