Sorry, I thought you were just asking about the tildas, not the syntax
of unique() in Scilab.
Please see
https://help.scilab.org/docs/6.0.2/en_US/unique.html
vs
https://fr.mathworks.com/help/matlab/ref/unique.html
Matlab syntax [C,ia,ic] = unique(___) with 3 outputs has no equivalent
in Scilab. i.e. in Matlab, after [C,ia,ic] = unique(A) then A=C(ic),
i.e. values in ic are the indices of corresponding unique value in C.
They can be recovered with the quick and dirty following loop:
for i=1:length(a)
ia(i)=find(a(i)==C)
end

[ans,ans,Minstances_hat] = unique(B(:));
gives: Wrong number of output arguments.
I also tried :
[Minstances_hat] = unique(B(:));
and get a vector.
also
[Minstances_hat,index] = unique(B(:));
seem to work.
However afterwards there is this line:
masks = reshape(Minstances_hat-1,size(B));
I try to convert via:
mask = matrix(Minstances_hat-1,size(B));
but no success.

Dear experts,
trying to convert a matlab code to scilab I come across following
line:
[~,~,Minstances_hat] = unique(B(:));
How to replace the "~" symbol?
by dummy names, e.g.
[ans,ans,Minstances_hat] = unique(B(:)); There is no equivalent mechanism
in Scilab.
B is the blue channel of a RGB image...hence a m x n matrix of
integers (type(B) = 8 )
Thank you,
Philipp
