Hello,

Is anyone having trouble logging into their ATOMS account? I'm unable 
to log in or create a new account.


Neither are we. Please have a look at

Hi, Pierre Payen
When running the script get the following error:

*--> exec('C:\Users\hermesr\Documents\Scilab
Xcos\Animations\penduleUpdated.sce', -1)
at line44 of executed file C:\Users\hermesr\Documents\Scilab
Xcos\Animations\penduleUpdated.sce

Invalid index.
*

And the animation is frozen.

 
Gracias

[Scilab-users] Plot Heart Curve in Scilab

2017-09-26 Thread Hermes 
Hello,
I've been looking at the forum, how to graph the following function:

x2=[-2:0.01:2];x1=[-1:0.01:1];
function val = Heart(x1, x2) 
val=(1.2*x2-sqrt(abs(x1)))^2+x1^2-1;
endfunction 

And I have not found anything to guide me. Please, could you help me?

 

Gracias
