Apply a function element-wise.

element-wise function
Do we have to process zero elements? true, false, auto: if auto, we will test
the supplied function for f(0) != 0
, and depending on the result, will
decide if we want evaluation for zero elements. WARNING: the AUTO setting
may not always work correctly for functions that are meant to run in a specific
backend context, or non-deterministic functions, such as {-1,0,1} random
generators.
new DRM with the element-wise function applied.
Slicing the DRM.
Slicing the DRM. Should eventually work just like in-core drm (e.g. A(0 until 5, 5 until 15)).<P>
The all-range is denoted by '::', e.g.: A(::, 0 until 5).<P>
Row range is currently unsupported except for the all-range. When it will be fully supported, the input must be Int-keyed, i.e. of DrmLike[Int] type for non-all-range specifications.
Row range. This must be '::' (all-range) unless matrix rows are keyed by Int key.
col range. Must be a sub-range of 0 until ncol
. '::' denotes all-range.
Map matrix block-wise vertically.
Map matrix block-wise vertically. Blocks of the new matrix can be modified original block
matrices; or they could be completely new matrices with new keyset. In the latter case, output
matrix width must be specified with ncol
parameter.<P>
New block heights must be of the same height as the original geometry.<P>
new matrix' width (only needed if width changes).
Parallelism adjustments.
Parallelism adjustments. <P/>
Change only one of parameters from default value to choose new parallelism adjustment strategy. <P/>
E.g. use
drmA.par(auto = true)to use automatic parallelism adjustment. <P/>
Parallelism here in API is fairly abstract concept, and actual value interpretation is left for a particular backend strategy. However, it is usually equivalent to number of map tasks or data splits. <P/>
If changed from default, ensures the product has at least that much parallelism.
if changed from default, ensures the pipeline product has exactly that much parallelism.
If changed from default, engine-specific automatic parallelism adjustment strategy is applied.
