  | ### 4.8.1 intmat declarations Syntax: `intmat` name `=` intmat_expression `;` `intmat` name `[` rows `] [` cols `] =` intmat_expression `;` `intmat` name `[` rows `] [` cols `] =` list_of_int_and_intvec_and_intmat_expressions `;` rows and cols must be positive int expressions. Purpose: defines an intmat variable. Given a list of integers, the matrix is filled up with the first row from the left to the right, then the second row and so on. If the int_list contains less than rows*cols elements, the matrix is filled up with zeros; if it contains more elements, only the first rows*cols elements are used. Default: 0 (1 x 1 matrix) Example:
        intmat im[3][5]=1,3,5,7,8,9,10,11,12,13;
        im;
      ==> 1,3,5,7,8,
      ==> 9,10,11,12,13,
      ==> 0,0,0,0,0
        im[3,2];
      ==> 0
        intmat m[2][3] = im[1..2,3..5];  // defines a submatrix
        m;
      ==> 5,7,8,
      ==> 11,12,13
