Re: [Scilab-users] Sound acquisition with Scilab under Linux
Hello, To handle a cross-platform sound handling in Scilab I suggest you to take a look at JIMS and the "Java Sound API". Not sure if it will fit your needs but might be. Note: another more advanced approach is to use SWIG-Scilab to generate the mapping of a library (Gstreamer might be a good cross platform candidate).

[Scilab-users] Function
Hi. I need your help. Is there a function for distance between two points? Thanks in advance. ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users
Re: [Scilab-users] Function
Hi Peter Q This question is just the strangest question I have ever seen on the Scilab forum. I'm not sure whether I shall think this is spam? ... alternatively, consider reading a Calculus book from high school. Possibly come back with a more well-defined question.

Re: [Scilab-users] Function
sqrt(sum((a-b).^2)) if your points are stored in vectors a and b. Best wishes, Jasper On 9/29/2015 15:58, Peter Q. wrote: Hi. I need your help. Is there a function for distance between two points?

Re: [Scilab-users] Function
I think you are missing brackets there, presuming .^ now operates on the sum? Best wishes, Jasper. On 9/29/2015 16:20, Serge Steer wrote: Le 29/09/2015 15:58, Peter Q. a écrit : Hi. I need your help.

If your points are given by cartesian coordinates stored in 2 arrays p1 and p2 you can compute the distance between these 2 points with norm(p2-p1) or equivalently by sqrt(sum(p2-p1).^2) Serge Steer Thanks in advance. ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users
Re: [Scilab-users] Function
Thanks guys for answer. Two points on plane; norm and sqrt work.

Hi, Le 29/09/2015 15:58, Peter Q. a écrit : Hi. I need your help. Is there a function for distance between two points? Thanks in advance. . Sharing the thoughtful skepticism of Claus, i would say: If the points are lying on a sphere and you are looking for the shortest direct arc linking them along the sphere, the Wikipedia page about spherical trigonometry might help you: https://en.wikipedia.org/wiki/Spherical_trigonometry Then, the usual cos(), and sin() Scilab functions will allow you implementing the relevant spherical formula. ;) Samuel Gougeon ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users
[Scilab-users] Strange behaviour with for loops
Hello, In the help, it is specified that the syntax 'for e = l ...' when l is a list is authorised. When l is replaced by a vector, the result appears to depend on whether its a column or row vector : With this code, the for loops runs 3 times and each time i is equal to another value of the vector idx idx =[1 2 3]; for i = idx disp("newIter") disp(i) end When the vector idx is a column vector now, there is only one loop and i is equal to the vector idx idx = [1 2 3]'; for i = idx disp("newIter") disp(i) end Is this behaviour intended?
