curve

问题 I have a dataset for curvature and I need to find the tangent to the curve but unfortunately, this is a bit far from the curve. Kindly guide me the issue solution related to the problem. Thank you! My code is as follows: fig, ax1 = plt.subplots() chData_m = efficient.get('Car.Road.y') x_fit = chData_m.timestamps y_fit = chData_m.samples fittedParameters = np.polyfit(x_fit[:],y_fit[:],1) f = plt.figure(figsize=(800/100.0, 600/100.0), dpi=100) axes = f.add_subplot(111) # first the raw data as a

问题 I'm tried to draw a bottom curve on UIimageview using uibezierpath. I don't know how to do that? - (void)setMaskTo:(UIView*)view byRoundingCorners: (UIRectCorner)corners { UIBezierPath *rounded = [UIBezierPath bezierPathWithRoundedRect:view.bounds byRoundingCorners:corners cornerRadii:CGSizeMake(200.0, 200.0)]; CAShapeLayer *shape = [[CAShapeLayer alloc] init]; [shape setPath:rounded.CGPath]; view.layer.mask = shape; } i already tried like this https://imgur.com/a/WKykdyU I expect the output

问题 I am trying to plot a curve on a sphere but I can not plot them at the same time. I identified some points with Euclidean norm 10 for my curve, and some other points to plot the sphere of radius 10 , respectively as following. Points for curve: random_numbers=[] basevalues=np.linspace(-0.9,0.9,100) for i in range(len(basevalues)): t=random.random() random_numbers.append(t*10) xvalues=[random_numbers[i]*np.cos(basevalues[i]) for i in range(len(basevalues))] yvalues=[random_numbers[i]*np.sin

问题 I have x array and y array. I need to predict points(points of pareto fronts) in left and right side (I don't know exactly how). That's why used in first extrapolation of points, but it gaves linear I tried to fit my data points to exponential curve, but gave me as result only straight line with coefficients A=1.0 , K=1.0 , C=232.49024883323932 . I also tried to fit my data to polynomial function with degree 3, result better, but the tail is increasing x=[263.56789586, 263.56983885, 263

问题 You will understand what I mean if you use graphic editing programs like Gimp or Photoshop. To edit a curve on those programs (which probably is Bezier Curve), we can click on the curve, drag the mouse and the curve is changed accordingly. I suspect all the things behind this mechanism are concerned with vectors, but I couldn't find any document mentioning how to do it. Could anybody tell me how I can do that? Thank you very much. [edit] What I meant was to select-the-curve itself to change

Here is my plan: Using kernel density function (like density()) with variant window width to calculate the density of this series. On every kernel curve with different window width, I find all the turning points
