How to get elements larger than x in a given range?

fixed the issue. Will look into that further Code. I'm trying to avoid matrix multiplication, so this may look a bit odd:
A = [1:5; 2:6; 3:7; 4:8; 5:9];

[r,c] = meshgrid(2:4,3:5);
n     = sub2ind(size(A), r(:), c(:));

indices = sort(n(A(n) > 5)); %'skip sorting if not needed'
values  = A(indices);
A = [1:5; 2:6; 3:7; 4:8; 5:9];

%'For column-first, 1-based-index array memory   '
%'layout, as in MATLAB/FORTRAN, the linear index '
%'formula is:                                    '
%'L = R + (C-1)*NR                               '
n = bsxfun(@plus, (2:4), (transpose(3:5) - 1)*size(A,1)); 

indices = n(A(n) > 5);
values  = A(indices);

Ruby math: take a number from a larger number range and calculate where it falls on a smaller range

Tag : ruby , By : tommy

This might help you If you want the value range to be linearly divided into equal sized subranges, this should do the trick for you:
min = scores.values.min
max = scores.values.max
nsub = adjectives.size
tresholds = (1..nsub).map do |n|
  min + (max - min) * (n / nsub.to_f)

scores.each_pair do |student, score|
  adj_index = tresholds.index {|t| t >= score }
  puts "#{student} score was in the #{adjectives[adj_idx]}."

Find the element in an array, in which left elements are smaller and right elements are larger?

Tag : arrays , By : mhedberg

will help you 1) scan the array from left to right, remembering the largest value so far;
2) scan the array from right to left, remembering the smallest value so far.

Setting matplotlib colorbar range (larger range than the values plotted)

Tag : python , By : Alex Sadzawka

it helps some times I finally managed to solve it. Instead of vmin and vmax, I must pass a keyword to control the levels to draw, like this:
import matplotlib.pyplot as plt
import numpy as np

rd = np.random.rand(40,100)
surface = 18 * rd           # maximum value will be 18

fig = plt.figure()
ax = fig.add_subplot(111)

cores = ax.contourf(surface[:], levels=range(41))
cbar = plt.colorbar(cores)


Identifying an assortment of lists whose elements make up the exact elements in a larger list

To fix the issue you can do I think that what you want to find is the set of the partitions of a multiset. To do so you can use sympy as follows:
from sympy.utilities.iterables import multiset_partitions
res=[p for p in multiset_partitions(["a","b","c","c","d"])]
[[['a', 'b', 'c', 'c', 'd']],
 [['a', 'b', 'c', 'c'], ['d']],
 [['a', 'b', 'c', 'd'], ['c']],
 [['a', 'b', 'c'], ['c', 'd']],
 [['a', 'b', 'c'], ['c'], ['d']],
 [['a', 'b', 'd'], ['c', 'c']],
 [['a', 'b', 'd'], ['c'], ['c']],
 [['a', 'b'], ['c', 'c', 'd']],
 [['a', 'b'], ['c', 'c'], ['d']],
 [['a', 'b'], ['c', 'd'], ['c']],
 [['a', 'b'], ['c'], ['c'], ['d']],
 [['a', 'c', 'c', 'd'], ['b']],
 [['a', 'c', 'c'], ['b', 'd']],
 [['a', 'c', 'c'], ['b'], ['d']],
 [['a', 'c', 'd'], ['b', 'c']],
 [['a', 'c', 'd'], ['b'], ['c']],
 [['a', 'c'], ['b', 'c', 'd']],
 [['a', 'c'], ['b', 'c'], ['d']],
 [['a', 'c'], ['b', 'd'], ['c']],
 [['a', 'c'], ['b'], ['c', 'd']],
 [['a', 'c'], ['b'], ['c'], ['d']],
 [['a', 'd'], ['b', 'c', 'c']],
 [['a', 'd'], ['b', 'c'], ['c']],
 [['a', 'd'], ['b'], ['c', 'c']],
 [['a', 'd'], ['b'], ['c'], ['c']],
 [['a'], ['b', 'c', 'c', 'd']],
 [['a'], ['b', 'c', 'c'], ['d']],
 [['a'], ['b', 'c', 'd'], ['c']],
 [['a'], ['b', 'c'], ['c', 'd']],
 [['a'], ['b', 'c'], ['c'], ['d']],
 [['a'], ['b', 'd'], ['c', 'c']],
 [['a'], ['b', 'd'], ['c'], ['c']],
 [['a'], ['b'], ['c', 'c', 'd']],
 [['a'], ['b'], ['c', 'c'], ['d']],
 [['a'], ['b'], ['c', 'd'], ['c']],
 [['a'], ['b'], ['c'], ['c'], ['d']]]

How do I find the largest contiguous n length range within a larger range

Tag : excel , By : 小和尚
Date : March 29 2020, 07:55 AM
I hope this helps . I am trying to find the cell references for the largest n length contiguous subset of values in my range. , Use this:
Function MaxN(n&, r As Range)
    Dim i&, j&, m#, t#, v, str
    v = r.Value2

    For i = 1 To UBound(v)
        If UBound(v) - i + 1 >= n Then
            t = 0
            For j = i To i + n - 1
                t = t + v(j, 1)
            If t > m Then
            m = t
            str = i
            End If
            Exit For
        End If
 MaxN = Range(Cells(str, r.Column), Cells(str + n, r.Column)).Address
End Function
