Basic Operations on OCaml matrices

Function: make : int -> int -> t

make nbrows nbcols
Return a matrix of size nbrows X nbcolumns with all coefficient initialized to 0. A null value for any parameter is accepted.

Function: copy : t -> t

Return a copy of the matrix.

Function: _print : t -> unit

Print in a unformatted way on the C standard output the matrix.

Function: get : t -> int -> int -> int

get vec row col
Return the corresponding coefficient of the matrix; in case of overflow during the conversion from pkint_t to int, raise exception Polka.Overflow.

Function: get_str10 : t -> int -> int -> string

get vec row col
Return the string representation in base 10 the corresponding coefficient of the matrix.

Function: set : t -> int -> int -> int -> unit

set vec row col val
Store the value val in the corresponding coefficient of the matrix.

Function: set_str10 : t -> int -> int -> string -> unit

set vec row col val
Store the value val represented in base 10 in the corresponding coefficient of the matrix.

Function: get_row : t -> int -> Vector.t

get_row mat row
Return a vector corresponding to the row row of the matrix mat. There is no sharing in memory between the result and the argument matrix.

Function: set_row : t -> int -> Vector.t -> unit

set_row mat row vec
Store in the row row of the matrix mat the vector vec. The coefficients are copied (no sharing memory).

Function: nbrows : t -> int

Return the number of rows of the matrix.

Function: nbcolumns : t -> int

Return the number of columns of the matrix.
