reshape() to something by 3 would be done as preparation for clustering by color, since the clustering routines expect the variables to go across the columns and that each row is a different sample.

reshape() is never mandatory. There is always a way to write for loops to copy the data into the desired new shape. reshape() is just fast and convenient.

With the later advantage of being able to see what are apparently the entire code, what you describe is the ‘F’ matrix, formed by reshaping an image. The purpose (from the code you posted earlier today in Can anyone help me out with the following code ? (link)) appears to be to provide an easy reference for replacing NaN values by a specific random row of ‘F’ later in the code.
It would be of significant benefit to us if you would post all the relevant code so we can see it and provide you with the information you want.
