4.4.2 intmat expressions
An intmat expression is:
- an identifier of type intmat
- a function returning intmat
-
intmat operations with int (
+,-,*,div,%) -
intmat operations (
+,-,*) - a type cast to intmat (see intmat type cast)
Example:
intmat Idm[2][2]; Idm +1; // add the unit intmat → 1,0, → 0,1 intmat m1[3][2] = _,1,-2; // take entries from the last result m1; → 1,0, → 0,1, → 1,-2 intmat m2[2][3]=1,0,2,4,5,1; transpose(m2); → 1,4, → 0,5, → 2,1 intvec v1=1,2,4; intvec v2=5,7,8; m1=v1,v2; // fill m1 with v1 and v2 m1; → 1,2, → 4,5, → 7,8 trace(m1*m2); → 56 |
