I got matrix, let's say, 100 rows and I would like to plot only 10-rows window of it.

Is it possible to add a slide control to Manipulate[] window so to shift 10-row "window" interactively?

I trying Manipulate[MatrixPlot[matrix[[x ;; x + 10]]], {x,0,100}], but that's not working.

Mistakes:

  • Element index starts from 1, not 0
  • Manipulate control x should run with step 1
  • Manipulate control x should run with up to 100 - 10 = 90, other wise you will exceed the max index

Here is a correct version

m = RandomReal[1, {100, 10}];
Manipulate[MatrixPlot[m[[1 + x ;; x + 10]]], {x, 0, 90, 1, Appearance -> "Labeled"}]

Would it be possible to make the above manipulate interactive a la .cdf? – WalkingRandomly Dec 2 '12 at 18:34
wow, thanks for your prompt answer! – Dennis Yurichev Dec 2 '12 at 18:52
@WalkingRandomly yes, definitely. Using Top Menu >> Deploy >> ... – Vitaliy Kaurov Dec 2 '12 at 19:53
@Vitaliy Yes I know that :) What I meant was 'why not do it in this answer?' – WalkingRandomly Dec 2 '12 at 19:58

@WalkingRandomly, it is not possible to embed the CDF itself as an answer. I think only images (and animated gif files) can be uploaded. May be someone can correct if I am wrong. – Nasser Dec 2 '12 at 20:04
