Solve equations stored in variables

Question

0 个投票

I have a code in which after the processing a numeric expression is stored in a variable 'Final'

and the numeric expression is (3206987*2^(3/10)*3^(29/40)*5^(23/40))/12000000

but when I do, disp(Final) it shows the entire numeric expression "(3206987*2^(3/10)*3^(29/40)*5^(23/40))/12000000" instead of solving this and printing out "1.841"

How do I get matlab to print out the solved solution instead of the numeric expression?

% This is the code, Normally "S" will be an input function.
close all 
clc 
clear 
syms w h
S = 0.1901*(w^(0.425))*(h^0.725);
Dsw = diff(S, w);
Dsh = diff(S, h);
first_term = Dsw*10;
second_term = Dsh*2.3;
Final1 = subs(first_term + second_term, w, 100);
Final = subs(Final1, h, 60);
disp(simplify(Final))
