There is a ResizeMatrix module that needs to be ported to SCIRun5, but it has bugs as well, so when it does get ported it will need to be fixed.

You could make a feature request in version 5 for a "ReshapeMatrix" module--it would be pretty easy to implement since the Eigen matrix library has a nice reshape function that does exactly what you want.

Hi Jess/Chris

I managed in the end by combining 4 times pairs of SelectSubMatrix with SetSubMatrix. To extract each row from the 1x16 vector and place it in the 4x4 matrix.

Kinda of convoluted :/

Of course I can create sub-module via GUI but those you cannot duplicate :(

So I might need the same amount of clicks in the end.

Anyway, thanks guys

Hi Peter,

I think Chris meant the SetSubMatrix module, which would perform as he describe.  I think it is column wise.  If it is not what you want, you can use EvaluateMatrixUnary to transpose it.

cheers,

Jess

You can create an empty 4x4 matrix and then use SetFieldData to populate it with the 1x16 vector. However, I can’t recall if SetFieldData performs this operation row-wise or column-wise.

Hello all,

how can I convert 1x16 to 4x4 matrix in scirun.

Spent 3 hours clicking around :(

Cheers,

Petar
