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

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

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.

Dear James I want to say that

if Z=even and N=even:

a,b,c,d,and f equal to these specific values

elseif Z=even and N=odd

a,b,c,d,and f equal to these specific values

and so on

how could I command them?

I just showed you how to code that. What I have written is the actual code for the conditional test. E.g.,

if( mod(Z,2)==0 && mod(N,2)==0 )
    % both are even
elseif( mod(Z,2)==0 && mod(N,2)~=0 )
    % Z is even and N is odd
etc.

Thank you so much it works
