Matrix: An fuzzy incident

Jonny Brown

The matrix has been used to solve linear equations for a long time. Until the 1800s, they were referred to as arrays. James Joseph Sylvester coined the term matrix (Latin for "womb," derived from mater - mother) in 1850, understanding a matrix as an object that gives rise to a number of determinants now known as minors, that is, determinants of smaller matrices derived from the original one by removing columns and rows. In 1913, an English mathematician named Cullis was the first to utilize current bracket notation for matrices, as well as the first important usage of the notation A = aij to express a matrix, where aij refers to the component in the I th row and the j th column.
