MATLAB: How could I solve the problem of if statement for even and odd values

even and odd

Whenever I inter any values of N and Z (even-even,odd-even,even-odd,odd-dd) I got only the last result in the condition
here is the code
Z=input('Z:   ')
N=input('N:   ')
if mod(Z,2)&& mod(N,2)
    a=-29.3860;b=-1.1561;c=1.5857;d=0;e=2050;f=0;
elseif   mod(Z,2)&& mod(N,1);   
    a=-29.0583;b=-1.016;c=1.6475;d=0.0426;e=-1.3405;f=6.8970;
elseif mod(Z,1) && mod(N,2);
    a=-31.6038;b=-1.0003;c=1.6943;d=2.6263;e=-3.5278;f=-0.0039;
else mod(Z,1)&& mod(N,1);
    a=-28.2580;b=-1.0811;c=1.6290;d=0.8047;e=-1.8276;f=3.6070;
end

Best Answer

mod(N,1) does not determine if a number is even or odd. You would want something like mod(N,2)==0 or mod(N,2)~=0. E.g.,
mod(Z,2)==0 && mod(N,2)==0 % both are even
mod(Z,2)==0 && mod(N,2)~=0 % Z is even, N is odd
etc.
