Solving a set of eqns in Matlab??

lucy123 · Apr 4, 2014

Hi I am trying to solve the following equations using Matlab for C1, C2, C3 and C4. In real fact I only require C1.

Code:

C1-C2-C3-1=0
n*C2+C3/n+(d-1)*C4=0
C1+b*C2-b*C3-1=0 
b*n*C2-b*C3/n-C4(1+d)=0

This is what I have input in Matlab but it seems its getting stuck because of the symbolic expresssion??

Any help please?

Code:

syms C1 C2 C3 C4 g L g_0 dL
n=exp(-g*L)
d=exp(-2*g_0*dL)
solve(C1-C2-C3-1, n*C2+C3/n+(d-1)*C4, C1+b*C2-b*C3-1, b*n*C2-b*C3/n-C4(1+d), C1)

It's a simple linear system of 4 equations, 4 unknown. It could be solved easily, even if the process is quite tedious.
