returns a random integer between the integer given by the first
int_expression and the one given by the second int_expression.
Syntax:
random ( int_expression, int_expression, int_expression )
Type:
intmat
Purpose:
returns a random intmat where the size is given by the second (number of
rows) and third argument (number of columns). The absolute value of the
entries of the matrix is smaller than or equal to the integer given as
the first argument.
Note:
The random generator can be set to a start value with
the function system, resp. by a command line option.
Example:
random(1,1000);
→ 35
random(1,2,3);
→ 0,0,0,
→ 1,1,-1
system("random",210); // start random generator with 210
random(-1000,1000);
→ 707
random(-1000,1000);
→ 284
system("random",210);
random(-1000,1000); // the same random values again
→ 707
