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

在 MATLAB Online 中打开

syms  b
G = 7340;
G1 = 4516.881;
M1 = 5222.328;  
M2 = 3264.034;
P1 = 3000;
P2 = 10000;
out=solve(G1 == G*(P1*exp(-b*M1/P1)/( P1*exp(-b*M1/P1)+ P2*exp(-b*M2/P2))), b)
out=double(out)
