Solving for power of a non linear equation in matlab












0















I have been trying to solve for n in the equation given below in matlab. All the rest of the values are known :
H_obs = 1*61 vector, dhdx = 1*61 vector, a = 1*61 vector. All the values of all the vectors are known



    a = (2*(10^-25)/(n+2))*((918*3.71)^n)*(H_obs.^(n+2))*(abs(dhdx).^(n-1))*dhdx;


Any tips on how to solve?
TIA

  • First factor has (n+2) in denominator and rest have it in exponent?

    Since you have 61 equations and 1 unknown, what you have is an overdetermined system - which means that you're not solving it, but rather finding an optimal solution in some sense. Take a look here.

  • Since it is nonlinear equation, you can use fsolve from Optimization Toolbox. You can find additional information on how to use it here: link
