# Solving Matrix Systems with Real, Interval, or Uncertain Elements

Solving Matrix Systems with Real, Interval, or Uncertain Elements

This Demonstration solves the system of linear equations given in the pane. Its size can be 2, 3, or 4. Set the elements (the real and uncertain parts) of the matrix and the right-hand side (rhs) vector for all the rows and columns by using the "value" slider.

The slider intervals for the real and uncertain parts of the uncertain number are and , respectively. These values are multiplied by , where ranges from -5 to 5. The slider jump is , where ranges from 1 to 6.
