单词 | matrix |
释义 | matrix Round brackets may be used instead of square brackets. The subscripts are read as though separated by commas: for example, a23 is read as ‘a, two, three'.

See addition (of matrices), block matrix, determinant, diagonal matrix, identity matrix, inverse matrix, matrix groups, matrix of a linear map, multiplication (of matrices), square matrix, trace, transpose, triangular matrix. |
