Sorry, I didn't include mlk definition.

load 'viewmat'
m1k=: (512%~512-~i.1024)j.~/419%~_825+i.1024
13 : 'x (+*:`] @. (2:<|)"0) y'

Compare these two images.

load 'viewmat' 
13 : 'x (+*:`] @. (2:<|)"0) y'
mandel2=: + *:`]@.(2: < |)"0
mm=. m1k mandel2^:3]m1k
viewmat mm
GRB=:1 0 2{"1 (#:i.8){0 255
GRB viewmat mm

In the second one, black is where the smallest numbers are located and the
white is the location of the largest numbers.

I figured it out: the left argument remains constant.

   13 : 'x (+*:`] @. (2:<|)"0) y'
+ *:`]@.(2: < |)"0
   mandel2=: + *:`]@.(2: < |)"0
   mm=. m1k mandel2^:3]m1k
