I have two variables as output from a simulink model, A and B.

A has 500001 rows and 1 column (5000001x1 double)
B has 500001 rows and 1 column (5000001x1 double)

I want a code which saves my data as .mat

save('AB.mat','A','B'); % save('FileName','Variables');

but only the half values of A and B respectivly.

For example,

A = [ 250001 250002 250003 ... 500001];
B = [ 250001 250002 250003 ... 500001];

You would have to define new variables, for example ‘Ahalf’ and ‘Bhalf’:

Ahalf = A(fix(size(A,1)/2):end);
Bhalf = A(fix(size(B,1)/2):end);
save('ABhalf.mat','Ahalf','Bhalf'); % save('FileName','Variables');

NOTE — This is UNTESTED CODE. However it should work.
