Efficient reshaping using data. Columns mult & red do not have values repeated. I'm not sure where you want to start the formulas, but the trick will be to use INDEX to pull out the value from 3x2 array that we want. How can we efficiently compute the partial trace of a matrix with Mathematica? There is some Mathematica code around to compute this, but most of it seems outdates and not very well written. Especially when you have to make big changes that a simple copy-and-paste won’t fix. The trace may be taken on any subset of the subsystems on which the matrix acts. The rows and columns of a matrix with this structure may be partitioned so that the entries of any bicluster in the Cartesian product of row clusters and column clusters are approximately constant. Meaning the creative star is far from dimming, creatives are just getting started on the good stuff. Some of the operations covered by this tutorial may be useful for other kinds of multidimensional array processing than image processing. Reshape an Array¶.
