This is also useful for the reader of this site, because it takes time to decode the program.Īlso plz note that Fortran has log() and log10() (the base is different), and also it is more accurate to use double-precision literal constants like 2.51d0. Fortran Program For Secant Method Numerical Code The Program I rewrote the function using my empirical derivation which took all factors besides D out of the function and got the same thing.Īlso, by pre-calculate the constant factors, I mean using some temporary variables to store constant factors as a whole, e.g.Ī hf(L 4Qpi) to make it easy to see the structure of the expression (not hard-coding the literal numbers). Units have also been checked multiple times, and I am certain that those are right. I originally solved this problem in excel using solver and was given 0.799 inches, reasonable for the size of this system (according to my mentor).Īs far as the solution goes, Ive tried cleaning up the parenthesis and ended up getting the same answers.
To avoid such issues, it is always useful to first arrange the expression for f(D) as simplest as possible before making a program. Fortran Program For Secant Method Numerical Update The Code.Fortran Program For Secant Method Numerical Code The Program.
