There is a external  module named ANN, you can find it at ATOMS:

Re: [Scilab-users] vectoriztion and sets of data

2012-11-22 Thread Adrien Vogt-Schilb


Hi again

I am still not sure, but look at the output of

A=rand(8,6)

B=zeros(8,6)

D = A > B

D = bool2s (A > B)

This might give you insight on how to solve your problem
tell me if not

Hi

Didn't understand your question, have a look at this:

A=[1:10]'*2

rows = [1;6;2]

B=zeros(A)

B(rows) = A(rows)


hope this helps

The original code looked like  Im trying to optimized it (ok for the if,
but how to combine a set of data and vectorization (??? Many trials but I
failed)

 

// initial matrix

A = rand(8,6);

B = zeros(8,6);

C = [A ; A; B; A; B; B; A];

[nr,nc] = size(C);

 

// original code looks like

D = zeros((nr/8),1);

for i = 1 : (nr/8)

search = max(abs(C((8*(i-1)+1):(8*i),:)));

if (search > 0) then

D(i,1) = 1;

else

D(i,1) = 0;

end

end

Hi,

I've seen the bug report http://bugzilla.scilab.org/show_bug.cgi?id=6737.
The report is 2 years old, can we still hope it will be fixed? 

Thanks,
