Please help me if you can. I wrote this but the answer still gives me the final condition only "not identified". What is the mistake ?
for PAs = 9
DAs = 8;
As = 131;
Bs = 3;
if PAs==0
DAs==0;
As==0;
Bs==0;
disp('specimen is sound')
elseif PAs==0:10
DAs==0:10;
As<100;
Bs<2;
disp('cap undercut')
else
disp('not identified')
end
end
not identified

The following conditional is seen as 'false' by the elseif statement.
elseif PAs==0:10
This will check PAs against every number in 0:10. It will only evaluate true (and execute the corresponding statement) if all conditions evalue 'true'
PAs=9;
PAs==0:10
ans = 1×11 logical array
0 0 0 0 0 0 0 0 0 1 0
If you want the elseif statement to execute if any of the comparisons is true, use any
any(PAs==0:10)
ans = logical
