Counting Possible Solutions for Linear Equations

Click For Summary
SUMMARY

The discussion focuses on utilizing the NSolve function in Mathematica to find multiple solutions for linear equations involving variables x1, x2, x3, and x4. Users reported obtaining approximately 14 different combinations for each variable. The conversation highlights the potential use of the Sow and Reap functions to count how often specific combinations occur when the equations are executed in a loop, suggesting a method for tracking solution frequency over multiple iterations.

Hi, I wondered if anyone can help. I have some linear equations in which I've found various possible solutions to the variables using NSolve function. For example, for x1, x2, x3 and x4, it has given me ~14 different possible combinations for each x. Is it possible to do a count so if the equations were run in a loop 1000 times, how often would a particular combination be reached?

I think that is the purpose of Sow and Reap, but I have never actually used them myself.
