The Equation for Fortran!
Discuss the history of Fortran!
The first FORTRAN compiler was a milestone in the history of computing,
at that time computers had very small memories (on the order of 15KB,
it was common then to count memory capacities in bits), they were slow
and had very primitive operating systems (if they had them at all).
At those days it seemed that the only practical way is to program in
assembly language.
Uses of Fortran!
Designed for scientific and technical (engineering) computing.
Example of Code.?
q’ = T(q,t)v
M(t,q)v’ = f(q,v,u,t) - L(q,v,u,t)*lamda
0 = H(q,t)v + k(q,t)
u’ = d(q,v,u,lambda,t)
