How do I include the row and column values say P = [2;4] into an equation where z = 10 + 2 (where 2 is the "x" cordinate of P? Thank you

p24 = P4-P2; 
p23 = Z_243*p24;
P3 = P2 + p23

%P3 outputs the values of% 
%%P3 = 
%        0.25
%        1.57

Now I want to add the value of 0.25 without typing 0.25 but the so called "x" cordinate of the P value into this equation

Xs = 10 + x

where x is actually 0.25, but I am unsure of how to assign the 0.25 as a variable of P

[KSSV]

P = [2;4] ;
z = 10+P(1) ; 

You should read about MATLAB array indexing.
