4.4.3 intmat type cast
-
Syntax: intmat (expression)intmat (expression, int_n, int_m)-
Type: intmat
-
Purpose: Converts expression to an intmat, where expression must be of type intvec, or intmat. If int_n and int_m are supplied, then they specify the dimension of the intmat. Otherwise, the size (resp. dimensions) of the intmat are determined by the size (resp. dimensions) of the expression.
-
Example: intmat(intvec(1)); → 1 intmat(intvec(1), 1, 2); → 1,0 intmat(intvec(1,2,3,4), 2, 2); → 1,2, → 3,4 intmat(_, 2, 3); → 1,2,3, → 4,0,0 intmat(_, 2, 1); → 1, → 2
