cubic spline (data cube)
显示 更早的评论
Consider the space-time data cube w(x, y, t) given in file datacube.mat, which loosely represents the displacement time history of a vibrating two-dimensional solid containing some localized spikes in the response. Visualize the data cube by performing an animation of the time frames. For each time frame, use cubic splines to interpolate the data and obtain a higher resolution rendering of the response at the selected time instant. You can use the Matlab built-in interpolation functions to spline the data. Try to conduct the most complete and detailed analysis you can.
I have no idea how to tackle this problem. Any tips how to solve the problem?
