How to get elements larger than x in a given range?
Tag : arrays , By : Edo

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)
end

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

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

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)

plt.show()

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)
            Next
            If t > m Then
            m = t
            str = i
            End If
        Else
            Exit For
        End If
    Next
 MaxN = Range(Cells(str, r.Column), Cells(str + n, r.Column)).Address
End Function
