We can divide the value by 10, round the result to zero precision, and multiply with 10 again. # Sort on last row, then on 2nd last row, etc. ), # Example on how to recognize NumPy scalars, # Gumbel distribution location=0.0, scale=1.0, # normalize histogram, i.e. List comprehension also makes it look very short and simple. Otherwise, it returns a dateTime with a timezone, If the timezone argument is empty, it returns a date without a timezone. We can divide the value by 10, round the result to zero precision, and multiply with 10 again. On behalf of the BioCAS 2015 Organizing Committee, This site is created, maintained, and managed by Conference Catalysts, LLC. The Quick Answer: Use multiple * (number / multiple). Depending on what the developer is doing, it may be impossible to use it. Consider an array Z = [1,2,3,4,5,6,7,8,9,10,11,12,13,14], how to generate an array R = [[1,2,3,4], [2,3,4,5], [3,4,5,6], , [11,12,13,14]]? ~100-1000 times faster for large arrays, and ~2-100 times faster for small arrays. How to read the following file? If integer is less than zero, the number is rounded to the left of the decimal point. Getting Python range() to recognise a decimal eg. Now I heard, that if for example 0.01 from a calculation isn't exactly the float 0.01 comparing them should return False (if I am wrong, please let me know). How to get the documentation of the numpy add function from the command line? Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. Required fields are marked *. Result: 0, Example: year-from-date(xs:date("2005-04-23")) --, Nice solution of v3.9 as well. Convert a vector of ints into a matrix binary representation (), #### 96. Or, for a set range instead of set data points (e.g. Consider 2 sets of points P0,P1 describing lines (2d) and a set of points P, how to compute distance from each point j (P[j]) to each line i (P0[i],P1[i])? Result: ("ab", "cd", "ef"), Example: remove(("ab", "cd", "ef"), 1) So I decided to test, whether there are any. @AndreTerra The problem is that @numpy@ is a third party package and adds a lot of overhead in terms of dependency-management, storage (for the package itself) etc. Summary of answer: If one has a sorted array then the bisection code (given below) performs the fastest. Consider an arbitrary array, write a function that extract a subpart with a fixed shape and centered on a given element (pad with a `fill` value when necessary) (), #### 81. Here's a simple case where rounding error causes arange to produce a length-4 array when it should only produce 3 numbers: range() can only do integers, not floating point. Using this function it's not necessary to import numpy, nor install it. Considering 2 vectors A & B, write the einsum equivalent of inner, outer, sum, and mul function (). #### 53. Given an arbitrary number of vectors, build the cartesian product (every combinations of every item) (), #### 91. Find indices of non-zero elements from [1,2,0,0,4,0] (), #### 11. First, for the example's sake, some data is simulated: We would like to fit this data with: model(t) = p0 * sin(2. I was also concerned, if there will be rounding mistakes. Feel free to do it and post it here. (), #### 94. (), #### 56. Rounds elements of input to the nearest integer. # 0. in ]-inf,-1[, f1 in [-1,+1], f2 in ]+1,+inf[, # Question: find x such that ||A*x-b|| is minimal, # Answer: x = pinvA * b, with pinvA the pseudo-inverse of A, # Relation with least-squares minimisation lstsq(), # Relation with singular-value decomposition svd(), # division gives a tupple with the quotient and remainder, # evaluate the polynomial in the values [1,2,3,4], # integrate polynomial twice and use [1,2] as integration constants, # fit a 2nd degree polynomial to the data, result is x**2 + 2x + 3, # fit a 1st degree polynomial (straight line), result is 8x-4, # peak-to-peak value for each of the 3 columns, # peak-to-peak value for each of the 2 rows, # if value array is too short, it is repeated, # also exists, but here FIRST indices, THEN values, # also exists, but here FIRST mask, THEN values, # same as linspace(1,10,4), 4 equally-spaced elements between 1 and 10 inclusive, # sequences separated with commas are concatenated, # return a matrix.
