Hint: the operation can be performed representing the rows of the matrix in grasshopper as vectors, and using the dot product as operator.

HI :-)

Sorry.. I have a task at my university, where I have been asked to do something, and do not understand how to make it?!

I have to make this:

I have made this

But do not understand have to make the last thing of my task, where I have been told: "Hint: the operation can be performed representing the rows of the matrix in grasshopper as vectors, and using the dot product as operator."

Fun... if you think about how matrix multiplication works, then you will see how you can decompose the matrix multiplication into vector operations.

/ a11 a21 a31 \ / b1 \

| a12 a22 a32 | | b2 | = ?

\ a13 a23 a33 / \ b3 /

[a1 a2 a3 ] dot [ b1 b2 b3 ] = ?
