A matrix can be thought of as columns of vectors. Matrices are the power tools for distributed computation involving linear algebra transformation. A variety of attributes or feature representation can be collected and operated upon via matrices.
In short, matrices are two-dimensional m x n arrays of numbers (usually real numbers) whose elements can be referenced using a two-element subscript, i and j:
A matrix is represented as follows:
A matrix transpose is represented as follows:
Matrix multiplication is represented as follows: ...
