Hello.. I hope you are doing great..

Some of the applications are as follows,

1. Computer vision (Used to calibrate camera, stitch together stereo images)

2.Control theory (Optimal controller can be found using simple linear algebra)

3 The key applications enabled by matrix theory in two major fields of interest in electrical engineering, namely wireless communications and signal processing

4.  Among the major applications in wireless communications, the role of matrix representations and decompositions in characterizing multiple-input multiple-output (MIMO) and orthogonal frequency division multiplexing (OFDM) communication systems is described.
