4.2.4 bigintmat operations
+
- addition with intmat, int, or bigint. In case of (big-)int, it is added to
every entry of the matrix.
-
- negation or subtraction with intmat, int, or bigint. In case of (big-)int,
it is subtracted from every entry of the matrix.
*
- multiplication with intmat, int, or bigint; In case of (big-)int, every entry
of the matrix is multiplied by the (big-)int
<>, ==
- comparators
- bigintmat_expression
[ int, int ]
- is a bigintmat entry, where the first index indicates the row and the
second the column
Example:
| | bigintmat m[3][4] = 3,3,6,3,5,2,2,7,0,0,45,3;
m;
==> 3,3, 6,3,
==> 5,2, 2,7,
==> 0,0,45,3
m[1,3]; // show entry at [row 1, col 3]
==> 6
m[1,3] = 10; // set entry at [row 1, col 3] to 10
m;
==> 3,3,10,3,
==> 5,2, 2,7,
==> 0,0,45,3
size(m); // number of entries
==> 12
bigintmat n[2][3] = 2,6,0,4,0,5;
n * m;
==> 36,18, 32,48,
==> 12,12,265,27
typeof(_);
==> bigintmat
-m;
==> -3,-3,-10,-3,
==> -5,-2, -2,-7,
==> 0, 0,-45,-3
bigintmat o;
o=n-10;
o;
==> -8, -4,-10,
==> -6,-10, -5
m*2; // double each entry of m
==> 6,6,20, 6,
==> 10,4, 4,14,
==> 0,0,90, 6
o-2*m;
==> ? bigintmat/cmatrix not compatible
==> ? error occurred in or before ./examples/bigintmat_operations.sing lin\
e 15: ` o-2*m;`
