Re: [Scilab-users] overloading concat "[ ]" operators

[Pierre Vuillemin]

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.

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

[Scilab-users] Nightly build w10 x64 5.5.2 or 6.0.0 b2 - Confusion between versions

[Perrichon]

Hello,

 

Today, the Nightly Buid server delivers the same version
scilab-master-1467282800_x64.exe, and display 6.0.0 when executing ver()
instruction.

So it creates a full confusion to distinguish bugs from 5.5.2 or 6.0.0, or
appreciates improvments.

 

Sincerely

Pierre
