I need a problem with 100 equations , it doesn't matter if it's linear or non-linear , if you can provide me with both I'd be really grateful, I hope this question gets answered within two days , the faster the better.
Note : I've been searching google for hours with no luck , that's why I need an expert that experienced a problem with 100 equations to solve .
Note : I'm not asking for the solution , I'm asking for the problem to solve.
note : I need a real life problem not make one myself.
Look up mean-variance optimization for stock portfolios. Go to yahoo finance or wherever and get some data for 100 stocks, compute the covariance matrix and there you go, a system of 100 equations from a non-madeup problem.
