I want to remane and reassigne some variable according 2 different cases
For example consider this script:
%In my script PBtime_b and PBtime_nb are obtained from other calculaion,
%(here i just assige a value) but im interested in a comparision between
%them in order to select other values
PBtime_b=5;
PBtime_nb=6;
Ab=5;
Cb=6;
Anb=7;
Cnb=8;
if PBtime_nb<=PBtime_b;
A=Ab
C=Cb
end
if PBtime_b>PBtime_nb;
A=Anb
C=Cnb
end
A
Unrecognized function or variable 'A'.
C
X=A+C
I would obtain A=Anb=5 and C=Cnb=6 but if i type A or C the script dosent recognize the variables
what i am doing wrong?

Hi Pierto
It is my understanding that you are facing "Unrecognized function or variable 'A'." error. And you want to rename and reassign some variable according to two different cases.
Please follow below updated code for the same in which you want to assign A=Anb= 5 and C= Cnb=6 as follows:
%In my script PBtime_b and PBtime_nb are obtained from other calculaion,
%(here i just assige a value) but im interested in a comparision between
%them in order to select other values
PBtime_b=5;
PBtime_nb=6;
Ab=5;
Cb=6;
Anb=7;
Cnb=8;
%you want A = Anb = 5 and C = Cnb = 6
if PBtime_nb>=PBtime_b;
A=Ab % Pbtime_nb = 6 > PBtime_b =5
C=Cb % A = 5, C = 6;
end
if PBtime_b>PBtime_nb;
Anb = A %Anb = 5
Cnb = C %Cnb = 6
end
A
C
X=A+C

Should be
if PBtime_nb>PBtime_b
instead of
if PBtime_b>PBtime_nb;

Since the cases appear to be mutually exclusive and non-independent, I don't see why the structure shouldn't be reduced to if-else.
if PBtime_nb<=PBtime_b;
A=Ab
C=Cb
else
A=Anb
C=Cnb
end

The OP's code with two separate if-statements is not wrong ...
