algorithmic modeling for Rhino
Are you using the latest version? I think back in 0.9.0014 the matrix components did not work yet.
Agreed. Notice the Slider does not rename to Rows and Columns
Good question, but Sorry I don't know why; I've never used matrices in Gh before. If you know a bit of Python, maybe you are better of installing numpy and scipy. However those libraries only work on Rhino 32bits and the latest gh version doesn't work there :'(
The Maths operators won't work on Matrices. I don't know if it is planned to or not.
If you want to use Native Grasshopper Components for Matrix Operations then you will have to deconstruct the matrix and then Data Match the required items, perform the operations and then recompile the End Product.
3x2 matrix multiplication with a 2x2 matrix
EDIT: you can obviously use your original Value list, I was just illustration the fact that you need to have the values not the Matrix
Thanks Danny learn your example. Can I use your algorithm for 5x5 matrices?
The Path Mapper doesn't do any calculations in that sense. What it does is allows you to assign data to different paths so that you have the ability to control the data matching at a much more advanced level.
There is no simple mapping for this particular Operation so you would have to break it up with list components to get the values to the correct calculation. What do you gain from this as opposed to using the Area component?
