4.6.2 intmat expressions

An intmat expression is:

1. an identifier of type intmat
2. a function returning intmat
3. an intmat operation involving ints and int operations (+, -, *, div, %)
4. an expression involving intmats and the operations (+, -, *)
5. 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
