Hi,
I am sub-classing numpy.ndarry for vector array representation. The append
function is like this:
def append(self, other):
self = numpy.append(self, [other], axis=0)
Example:
vary = VectorArray([v1, v2])
#vary = numpy.append(vary, [v1], axis=0)
vary.append(v1)
The commented synt
Hi,
I am doing a little test using numpy and numexpr to do a particle simulation. I
never used either of them much and this is the first time I have to go deeper.
Here is the code:
import numpy as np
import numexpr as nexpr
class Particle( object ):
def __init__( self, id ):
s
Well,
I came up with a slightly different approach.
Get the first row on the image.
It would be something like this:
[1,1,1,0,0,0,1,1,0,0,1]
1 = white, 0 = black.
Run the floodfill on [0],[6] and [10] pixel
if floodfill area is smaller then given area then paint that area black
if floodfill area
Hi,
This a little wiered problem. I am having a black and white image. (black
background)
Entire image is filled with noisy white patterns of different size and shape. I
need to fill the
white patches if there area is more then given one. Logically this could

Hi,
I am new to numpy and getting my hands on slowly.
How do you replace integers from strings in an integer array. (1D)
For example:
array = {1,1,1,2,3,3,4}
replace 1 with "apple"
replace 2 with "cheery"
replace 3 with "mango"
replace 4 with "banana"
I know the general solution, but I am lo

If you want appending in place you have to use a python list. If you don't
need modification in place, np.append returns
How do I solve this?

es you need,
along with c++ routines for I/O, manipulation and
(OpenGL) display, and a python interface.

Hi,
I have never used numpy in my python applications until now. I am writing a
python/openGL based tool to manipulate 3d geometrical data(meshes, curve,
points etc.) I would be using numpy to store these objects(vertices, edges,
faces, index etc.) at run time. One of my major concern is numpy'
Hi,
numpy rocks!!!
import numpy
linsp = numpy.linspace
red = linsp(0, 255, 50)
green = linsp(125, 150, 50)
blue = linsp(175, 255, 50)
array's elements are float. How do I convert them into integer?
I need to build a new array from red, green, blue. like this:
[[ red[0], green[0], blue[0] ],
