Is there a way to color the calculated surface just after the integral between two bounds? 回答1: I suppose that your function is called with g(x) as in your previous post. The following should do what you

问题 I have two lines: y = -1/3x + 4 y = 3x + 85 The intersection is at [24.3, 12.1] . I have a set of coordinates prepared: points = [[1, 3], [4, 8], [25, 10], ... ] #y = -1/3x + b m_regr = -1/3 b_regr = 4 m_perp = 3 #(1 / m_regr * -1) distances = [] points.each do |pair| x1 = pair.first y2 = pair.last x2 = ((b_perp - b_regr / (m_regr - m_perp)) y2 = ((m_regr * b_perp) / (m_perp * b_regr))/(m_regr - m_perp) distance = Math.hypot((y2 - y1), (x2 - x1)) distances << distance end Is there a gem or

问题 The coordinate of the system is boundary coordinates (x_min, y_min, x_max, y_max). and I want to find the intersection of two boxes set1 and set2 set1 -> (n1,4) set2 -> (n2,4) example set_1-> tensor([[0.2400, 0.2342, 0.8500, 0.8048], [0.1420, 0.5075, 0.2440, 0.5856], [0.0000, 0.5075, 0.1420, 0.5976]], device='cuda:0') set_2-> tensor([[-0.0368, -0.0368, 0.0632, 0.0632], [-0.0576, -0.0576, 0.0839, 0.0839], [-0.0576, -0.0222, 0.0839, 0.0485], ..., [ 0.0000, 0.0000, 1.0000, 1.0000], [ 0.0000, 0

问题 I just started to work with 3D meshes, oriented to be used for finite element analysis. I would like to model inclusions for materials (any shape, but mainly interested in spheres and ellipsoids) in a cube-like matrix. These inclusions shouldn't be coincident with each other. So I was thinking to use some sort of package for python which can plot primitive objects, look for their intersection (if it exists) and export the geometry (or mesh it and export it). In case of spheres, I was coding

问题 Currently I am stuck trying to find the intersection of three sets. Now these sets are really lists that I am converting into sets, and then trying to find the intersection of. Here's what I have so far: for list1 in masterlist: list1 = thingList1 for list2 in masterlist: list2 = thingList2 for list3 in masterlist: list3 = thingList3 d3 = [set(thingList1), set(thingList2), set(thingList3)] setmatches c = set.intersection(*map(set,d3)) print setmatches and I'm getting set([]) Script terminated
