mathplotlib imshow complex 2D array

心不动则不痛 提交于 2021-02-06 08:55:26
问题 Is there any good way how to plot 2D array of complex numbers as image in mathplotlib ? It makes very much sense to map magnitude of complex number as "brightness" or "saturation" and phase as "Hue" ( anyway Hue is nothing else than phase in RBG color space). http://en.wikipedia.org/wiki/HSL_and_HSV But as far as I know imshow does accept only scalar values which are then mapped using some colorscale. There is nothing like ploting real RGB pictures? I thing it would be easy just implement a

How do I initialize a two-dimensional List statically?

问题 How can I initialize a multidimensional List statically? This works: List<List<Integer>> list = new ArrayList<List<Integer>>(); But I'd like to init the list with some static lists like: (1,2,3), (4,5,6) and (7,8,9) 回答1: If you create a helper method, the code looks a bit nicer. For example public class Collections { public static <T> List<T> asList(T ... items) { List<T> list = new ArrayList<T>(); for (T item : items) { list.add(item); } return list; } } and then you can do (with a static

问题 I have a multidimensional associative array with a type property. It looks like this: $data = array( array( "name" => "SomeName", "type" => "A"), array( "name" => "SomeName", "type" => "A"), array( "name" => "SomeName", "type" => "A"), array( "name" => "SomeName", "type" => "A"), array( "name" => "SomeName", "type" => "A"), array( "name" => "SomeName", "type" => "B"), array( "name" => "SomeName", "type" => "B"), array( "name" => "SomeName", "type" => "B"), array( "name" => "SomeName", "type"

numpy-like package for node

问题 During my years on Python development, I've always been amazed at how much much much faster things become if you manage to rewrite that code that loops though your ndarray and does something, with numpy functions that work on the whole array at once. More recently I'm switching more and more to node, and I'm looking for something similar. So far I have turned up some things, none of which look promising: scikit-node, runs scikit-learn in python, and interfaces with node. I haven't tried it,

问题 according to my task I need to read a file passed as a command line argument using C and store its content (each character) to an 2D array to be able change array's values later and save the changed content to another file. NVM some custom functions. Here is an example of a file I need to read: #,#,#,#,#,#,.,#,.,.,.$ #,.,#,.,.,#,.,#,#,#,#$ #,.,#,.,.,.,.,.,.,#,#$ #,.,#,.,.,#,#,#,#,#,#$ #,.,.,#,.,.,.,.,.,.,#$ #,.,.,.,#,.,#,#,.,.,#$ #,.,.,.,.,#,.,.,.,.,#$ #,.,.,.,.,#,.,.,.,.,#$ #,.,.,.,.,.,.,.,.

问题 How do I sort a multidimensional array by a value, but with a custom order? The multidimensional array will be something like: $attribute_content[0]['term_id'] = 76; $attribute_content[0]['content'] = "ratio"; $attribute_content[1]['term_id'] = 18; $attribute_content[1]['content'] = "ideal condition"; $attribute_content[2]['term_id'] = 164; $attribute_content[2]['content'] = "genotype"; $attribute_content[3]['term_id'] = 218; $attribute_content[3]['content'] = "genetics"; $attribute_content[4
