Simple one I guess : I would like to get from a Vector (1x8) to a Matrix (2x4) using index selection from one or two external constant block(s).
I tried using the assignment block but I guess I don't really understand how to use it here. Expected output is in yellow.

As Fangjun noted, MATLAB Function block is a good approach.
It can also be done with a combination of reshapes and selector.

Your output is a 2x4 matrix. Using Assignment block, you could either
Provide a scalar value in U, assign multiple elements of the 2x4 matrix
Or, Provide the same size (2x4) value in U, assign seletive elements of the 2x4 matrix.
I couldn't figure out a way to do what you want, which is reshape plus shuffle.
The easiest approach is to use a MATLAB Function block. It just needs one line of code.
