What is the difference between argmaxabs() and maxabs()?
Feature Request : What about variation of narg? I would like to have nargnonzero to count all of the number of nonzero value within a vector? That’s one variation. The recent commit I did reminded me that maybe this should be a thing.
Another question, what in the world is cbrt()?
\sqrt[3]{x}
I got that after looking for it in google. I prefer to use x^(1/3) myself, but now I know.
cbrt() may be faster than x^(1/3) and calculates cbrt(-27) to -3, wehereas x^(1/3) for x = -27 should give a NaN
I discovered cbrt() recently too. This is what @David_Tschumperle told me in a PM
This computes the minimal of the absolute values of image pixels. You could achieve something similar, e.g. with:
$ gmic img1.jpg img2.jpg +abs min[-2,-1]
but this means duplicating the images, applying the abs, then the min, while
absmindoes that in a single shot, without need to duplicating the image data.
So I believe we can think of
in the same way: abs then argmax and abs then max.
I had to read it multiple time to get it, but thank you for the clarification. The feature request part haven’t been typed about though.
