2.3 Using Computers to Solve System of Linear Equations

The systems of linear equations that you have encountered up to this point may have been nearly as simple as the system derived by Professor Tapia. Solving a system of this size is relatively easy and not necessarily time consuming, so we can get by without a computer. But performing multiplications, additions, and substitutions on larger systems quickly becomes tiresome and error prone. Yet it is common for linear systems associated with real-world problems to have thousands of equations and thousands of unknowns. These are the types of systems that computational scientists solve daily using computers.
