# Custom solution for 3 non-linear simultaneous equations 1.0

Date Added: July 07, 2013  |  Visits: 226

This customised function solves one type of non-linear systemof 3 simultaneous equations in 3 unknowns: k, L and r0 in 3 equations with 4 knowns: zeta, eeta, d and angle.function matrixresults = symsolvenonlineq(n,degrees,dinput)% EXAMPLE USAGE: m=symsolvenonlineq(3,45,20)% nb: takes around 738s to process two 1 x 1000 matricesINPUT Parameters:% n determines size of a random matrix for zeta and eeta,% degrees is the angle and sets constant 'angle' (in radians),% dinput sets constant 'd'.%%OUTPUT:%returns a 2D matrix of results for k,L and r0.%%5 things to note:%1/ you need to do a 'clear all' prior to running the function%otherwise it may crash on big input matrices;%2/ could not use 'zeta' with 'solve' as it gave an error so%shortened variable 'zeta' to 'zet';%3/ always produces a complex solution set for k, L and r0.%4/ always get 2 complex solutions for each of k, L and r0.%5/ function returns 1 complex solution times n for k, L and r0.
