Scilab - How to get the maximum absolute value in a Matrix with its original sign?

Question

I am using Scilab 5.5.2

I am trying to get the maximum absolute value in a vector.

See this example

a = [-9;-19;11]

If I type:

max(abs(a))

I get:

That's close to what I want. Yes, 19 is the maximum absolute value. However, I would like to have the maximum absolute value in its original form, in this case, as -19.

How can I solve this? Is there a command in Scilab especially designed for that?

I tried looking at documentation but couldn't find.

You can find where the maximum happens and then get the value there:

[word, idx]=max(abs(a));
maximum=a(idx);

Could you help me to adapt this for Scilab? – May 25 '17 at 19:02

@Harry I have not scliab in my PC, but reading the docs, this should work I think. Perhaps you need `[m, idx]=max(abs(a));` – Ander Biguri May 25 '17 at 19:03
