4.6.3 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, intmat, or bigintmat. 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. If expression is a bigintmat containing an entry larger the the limit of int, it is set to 0 in the returning intmat.

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 bigintmat bim[2][3]=34, 64, 345553234, 35553, 6434, 6563335675; intmat(bim); ==> 34,64,345553234, ==> 35553,6434,0
