vector3d random sample
조회 수: 1(최근 30일)
I have a problem plotting some data. There are too many points and therefore I want to plot a random sample.
The class is vector3d and contains 13717 points. I would be interested in plotting around a 1000 points or just a certain percentage. However, I keep getting the following error:
'Error using reshape
Product of known dimensions, 3, not divisible into total number of elements, 13717.'
Hope anyone here can help me.

vector3d is not a MATLAB class. In case you have data points in the form of n*3 matrix. You can do something like this
M = rand(13717, 3); % for example
idx = randperm(size(M,1), 1000); % select 1000 points from 13717
M_small = M(idx, :); % 1000x3 matrix
