Definition of identity matrix in English:

identity matrix

noun

Mathematics

A square matrix in which all the elements of the principal diagonal are ones and all other elements are zeros. The effect of multiplying a given matrix by an identity matrix is to leave the given matrix unchanged.
〔数〕单位矩阵
Example sentencesExamples
- The variance-covariance matrix of residuals is, where R is an identity matrix.
- The matrix I is the identity matrix with ‘ones’ on the diagonal and ‘zeros’ off the diagonal.
- Consider the simple example that arises from regarding the 3 x 3 identity matrix as a co-occurrence matrix.
- Here G is the geometry matrix, and I is the identity matrix.
- The prior correlation matrix was assigned to be the identity matrix, i.e., R = I.
