Hi
Is there a way to do linear algebra in sc, specifically matrix multiplication (matrix with matrix, matrix with vector,etc) ? thanks Miguel Negrão _______________________________________________ sc-users mailing list sc-users@... http://lists.create.ucsb.edu/mailman/listinfo/sc-users |

In the MathLib Quark there's a Matrix class that I haven't used but
might be worth looking into. ~luke On Mon, May 12, 2008 at 7:26 AM, Miguel Negrao <miguel.negrao@...> wrote: > Hi > > Is there a way to do linear algebra in sc, specifically matrix > multiplication (matrix with matrix, matrix with vector,etc) ? > > thanks > Miguel Negrão > _______________________________________________ > sc-users mailing list > sc-users@... > http://lists.create.ucsb.edu/mailman/listinfo/sc-users > sc-users mailing list sc-users@... http://lists.create.ucsb.edu/mailman/listinfo/sc-users |

Yes, I haven't used that class either but you may find it useful.
In fact matrix multiplication can be written fairly compactly in plain SC: a = [[1, 0, 2], [-1, 3, 1]]; b = [[3,1], [2,1], [1,0]]; a.collect{|row| (row * b).sum } Dan 2008/5/12 Luke Selden <lselden@...>: > In the MathLib Quark there's a Matrix class that I haven't used but > might be worth looking into. > > ~luke > > > > On Mon, May 12, 2008 at 7:26 AM, Miguel Negrao > <miguel.negrao@...> wrote: > > Hi > > > > Is there a way to do linear algebra in sc, specifically matrix > > multiplication (matrix with matrix, matrix with vector,etc) ? > > > > thanks > > Miguel Negrão > > _______________________________________________ > > sc-users mailing list > > sc-users@... > > http://lists.create.ucsb.edu/mailman/listinfo/sc-users > > > _______________________________________________ > sc-users mailing list > sc-users@... > http://lists.create.ucsb.edu/mailman/listinfo/sc-users > -- http://www.mcld.co.uk _______________________________________________ sc-users mailing list sc-users@... http://lists.create.ucsb.edu/mailman/listinfo/sc-users |

My personal opinion (just 2p worth) is that it's not appropriate for
the core Array class since it's only applicable to a particular sort of array. The Matrix class add-on does include matrix multiplication etc, makes more sense there. By the way, instead of "if( this.flop.size == matrix.size)" use "if( this[0].size == matrix.size)". Why? Because .flop is pretty heavy duty for big matrices, so worth avoiding...

That would definetelly be usefull. As Luke said, the MathLib quark provides a Matrix class. Read the "Quarks" helpfile if you're not familiar with quarks - SC's way to manage language extensions.

If you've never used Quarks before you probably need to checkout the
Quarks. I'm not at supercollider at the moment but in the Quarks helpfile I think it has the line Quarks.checkoutAll run that and a terminal window should pop up asking you to accept a svn certificate (sp?) -- select "P" and then it will download all the quarks for you. hope that helps- ~luke On Mon, May 12, 2008 at 1:40 PM, Miguel Negrao <miguel.negrao@...> wrote: > nescivi escreveu: >> On Monday 12 May 2008 15:35:05 Miguel Negrao wrote: >>> Dan Stowell escreveu: >>>> My personal opinion (just 2p worth) is that it's not appropriate for >>>> the core Array class since it's only applicable to a particular sort >>>> of array.
