Matlab Maci64 R2012a
This bothers me greatly. I am creating an evenly spaced array on the fly for several particles that I integrate using ode45. I then place the answer on an interpolated timeline so that i can easily align the particles for animations, etc...
After having collected a large data set, I noticed the following, linspace is not accurate, even when it really should be.
try this:
linspace(0,1,401)'
then
linspace(0,10,401)'
This is a problem as I tried using unique to help me determine the final number of interpolated steps I had generated using the solver, only to find that there were several values on my timeline which differed by 1e-15.
Why can't linspace behave? When dealing with fractions of low integers, it really should not introduce artifacts in the numbers. Of course, I can solve my problem in a number of other manners, but still, linspace should generate artifacts, or perhaps it should have an added option to place the numbers within a certain accuracy?
