## 4.6 intmat

Integer matrices are matrices with integer entries. For the range of integers see Limitations. Integer matrices do not belong to a ring, they may be defined without a basering being defined. An intmat can be multiplied by and added to an int; in this case the int is converted into an intmat of the right size with the integer on the diagonal. The integer `1`, for example, is converted into the unit matrix.
