Help plotting piecewise function?

I'm new to matlab and was wondering if someone could help me plot the following function as I don't really know where to start....

x is an integer value between 1 to 10

V_{x}N= if x is even, [(3/x)*(3/(x-2))...*(3/4)]*2*N^x

if x is odd, [(5/x)*(5/(x-2))...(5/3)]*pi

N is arbitrary but a value of N=1 is passed into the function in order to plot it

[Aye]

I'm thinking of creating an if else statement with the following structure

if (mod(x,2)==0)

eq1

else

eq2

end

but am having trouble figuring out how to code the equations

for x = 1 : 1 : 10
    if mod(x,2) == 0
    y(x) = [(3/x)*(3/(x-2))...*(3/4)]*2*N^x 
        else
    y(x) = [(5/x)*(5/(x-2))...(5/3)]*pi
    end
end    

Vector y contains your functions from 1 to 10, then you'll have probably have to use for again to plot each on its interval if I understood correctly.

YOu can proceed like this:

x = 1:10 ; 
y = zeros(size(x)) ; 
N = 1 ; 
% x is even 
idx = 2:2:length(x) ; 
y(idx) = [(3./x(idx)).*(3./(x(idx)-2))*(3/4)]*2.*N.^x(idx) ; 
% x is odd 
idx = 1:2:length(x) ; 
y(idx) = [(5./x(idx)).*(5./(x(idx)-2))*(5/3)]*pi ;

plot(x,y)
