Matrices are used to represent real-world data about specific populations, such as the number of people who have a specific trait. They can also be used to model projections in population growth.

In the field of computing, matrices are used in message encryption. They are used to create three-dimensional graphic images and realistic looking motion on a two-dimensional computer screen and also in the calculation of algorithms that create Google page rankings. Matrices are used to compress electronic information and play a role in storing fingerprint information. Errors in electronic transmissions are identified and corrected with the use of matrices.

Many scientific fields use very practical applications of matrices.

  • In the field of medicine, CAT scans and MRI's use matrices.
  • In geology, they are used in taking seismic surveys.
  • In robotics, they are used to calculate movements.
  • In physics, matrices are used to study electrical circuits and quantum mechanics
  • Matrices are used to calculate battery power output and resistor conversion of electrical energy.
