I have a very long Excel data sheet of z-values. I converted the Excel sheet into CSV. to make it less heavy on calculation time.
The data is divided into packs of $197\times197$. After every pack there is a row with only zeros to divide the packs. For every block, I would like to plot a contour plot. Therefore I need to extract the individual blocks.
Something like: Split at every 197*197 Element, but skip 1*197 Element after each split (row for separation) How can I do that?
Thanks for any help!
