You can use matrices to design IC chips, design race cars, plan the trajectory of a spaceship, path-plan for a robot: just about any fancy engineering that you can think of. Electrical engineering has complex numbers in just about in every thing. When you solve equations, sometimes you cannot get "real" answers, and resort to complex roots. Root solving is used for studying such things as the stability of an aircraft, ship, automobile, building, etc. You can't do any serious engineering without matrices and complex numbers.

Matrices are used everywhere in engineering. If you want to solve a bunch of linear equations simultaneously, matrices are the way to go. Of course they are also useful in differential equations and many more useful areas. One striking use is in computer graphics! While you play a 3D shoot 'em, you should be aware that your computer is making tons of matrix computations in miliseconds to bring you those images very fast.
As for complex numbers, any electronics engineer will tel you that understanding complex numbers is essential.
Of course these concepts are a lot useful in pure mathematical research too but that is not much practical.

In electronics you use the matrix to apply various equations such as V=i*r to a group of circuits to design the layout for something such as a circuit board or buildings electric configuration. Sometimes the charges are negative and sometimes positive. If you need to calculate them all at moment you will need imaginary numbers to represent the math applied to the negative charge.
Other applications of matrix numbers include structures, mechanical functions, and multiple chemical reactions brought about by one catalyst.

The concept of matrix is also used in computer programming. Complex numbers is particularly useful in the field of electrical engineering.

Matrix can be used to solve a group of simultaneous linear equations
Complex numbers can be used in solving circuits where inductance and capacitance cause phase relationships between current and voltage to change.

A matrix is a shorthand way of describing simultaneous linear equations. The coefficients of the equations are important, more than the variables.

In computer graphics you use matrices when moving 2d or 3d objects. They allow you to rotate objects around so you can view them from infinite number of perspectives. you multiply the relativity of all the points in an object to the mouse by one matrix and it will spin it around on the screen. It is very quick and not very costly compared to other ways to rotate objects

Matrices are used for representing systems of equations, among other things. Aside from that, the use I find most interesting is the application of those matrices to crypography. You can read about one such cipher here: http://www.mathforum.org/library/drmath/view/51593.html
I have my doubts about its security, but it's still interesting.

most of the engineering calculation the compex no used to check stability of the system and matirx is used to simplify the complex algeribra its easy than other methods
