# Math Help - Solving linear equations

1. ## Solving linear equations

I have an equation of the form Ax=Y where A is the coefficient sparse matrix of size m*n. I want to solve for x where m > n and a different one where m< n. [m and n > 1000] What is the best method to solve such problems: direct and iterative solution? I appreciate any suggestion!

2. Since m and n > 1000, I suggest you used specialized software, like matlab to solve it, since it would take you too long by hand.
