FreeMat

Statement of Purpose
Learn the basic functions with graphing functions and solving system of linear equations by matrix operations.

Procedure

Graph two sine waves with different phase.

Set up a matrix and solve a circuit by using inverse matrix and Ohm's Law

 Graph two sine waves and the superposition of both waves.

Change the angular frequency of the function.

 

 This the resulting graph. Notice the change in the x-axis.

Conclusion

Freemat is very useful for calculating arithmetic problems, solving linear equations, basic matrices operations, and graphing functions.
