Hi Philippe,
You can create another object, a matrix of bing int that stacks your
bigint in a list, i.e.
x = tlist(["bigint","rep","signe"],[7654321;5678998;1234],1)
y = tlist(["bigint","rep","signe"],[3456789;5432112;9876],1)
X = tlist(["mbigint","entries"],list(x,y))
Then you can overload the display for "mbigint" for instance with
function %mbigint_p(e)
str = ""
for i = 1:length(e.entries)
for j =length(e.entries(i).rep):-1:1
str = sprintf("%s%d",str,e.entries(i).rep(j))
end
str = str +"\n"
end
printf(str)
endfunction
If you want to make matrix (not only vectors), then you need to add the
size of the matrix as an attribute of "mbigint" and reshape the display
accordingly.
Pierre.

Hi,
I have created a simple data structure to handle "big integers" . It
is
based on scilab tlist and named "bigint" . I have overloaded basic
unary/binary operators for bigint (like +,*,-,/,^,==,<,>,... ) :
-->x=bigint('123456789987654321')
x =
123456789987654321
-->y=bigint('987654321123456789')
y =
987654321123456789
-->z=x-y
z =
-864197531135802468
but now I want to create matrix of bigint so I need to create
functions like %bigint_c_bigint and %bigint_f_bigint . I try using
"cell" It's not exactly what I was expecting : matrix entries are
displayed as tlist instead of bigint display (modified via %bigint_p )
-->T=cell()
T =
[]
-->T(1).entries=x
T =
tlist(["bigint","rep","signe"],[7654321;5678998;1234],1)
-->T(2).entries=y
T =
!tlist(["bigint","rep","signe"],[7654321;5678998;1234],1) !
! !
!tlist(["bigint","rep","signe"],[3456789;5432112;9876],1) !
-->T(3).entries=z
T =
!tlist(["bigint","rep","signe"],[7654321;5678998;1234],1) !
! !
!tlist(["bigint","rep","signe"],[3456789;5432112;9876],1) !
! !
!tlist(["bigint","rep","signe"],[5802468;9753113;8641],-1) !
how could I get a display like
-->T
T =
! 123456789987654321 !
! !
! 987654321123456789 !
! !
! -864197531135802468 !
actually I only get
-->T.entries
ans =
ans(1)
123456789987654321
ans(2)
987654321123456789
ans(3)
-864197531135802468
