function [A,B] = spec_convert(C,D,typein,typeout)
% typein: 'abs' or 'rel' or 'ana'
% typeout: 'abs' or 'rel' or 'ana'
% C, D: input specifications
% A, B: output specifications
%
% Enter your code below.
if typein == abs && typeout == abs
A = C;
B = D;
elseif typein == abs && typeout == rel
A = -20*log10((1-C)/(1+C));
B = -20*log10(D/(1+C));
elseif typein == abs && typeout == ana
Rp = -20*log10((1-C)/(1+C));;
As = -20*log10(D/(1+C));
elseif typein == rel && typeout == rel
A = C;
B = D;
elseif typein ==rel && typeout == abs
K = 10^(C/20);
d1 = (K-1)/(K+1);
d2 = (1+d1)*(10^(-D/20));
elseif typein == rel && typeout == ana
e = sqrt((10^(-0.1*C))-1);
A = 10^(0.05*D)
end
end

Use the strcmp or strcmpi function to compare character arrays:
if strcmp(typein,'abs') && strcmp(typeout,'abs')
Do this similarly for the other tests.
