Dear Matlab experts,
I coded in Matlab to get the b value.
syms b
G = 7340;
G1 = 4516.881;
M1 = 5222.328;
M2 = 3264.034;
P1 = 3000;
P2 = 10000;
solve(G1 == G*(P1*exp(-b*M1/P1)/( P1*exp(-b*M1/P1)+ P2*exp(-b*M2/P2))), b)
But I got this in Matlab.
ans =
(65970697666560000*log(9312156501286059/49663631807804870))/93307147182466409
I would like to get the number, so please let me know how to fix this.
Thank you very much in advance.
Sincerely yours,
Redwood

out=solve(G1 == G*(P1*exp(-b*M1/P1)/( P1*exp(-b*M1/P1)+ P2*exp(-b*M2/P2))), b)
out=double(out)
