I often get the error 'cannot save points as a float matrix' while I'm trying to plot with the spacecurve command.
loodl2 is a 4 component vector, loodl2c is the 3 component variant.
loodl2:=T1.<loodl,1>: loodl2c:=<loodl2, loodl2, loodl2>
loodlpl:=spacecurve(loodl2c, k=-10..10, color=red):
also with this syntax:
and this syntax:
l2c1:= 2*k: l2c2:=0, l2c3:=8-k:
spacecurve([l2c1, l2c2, l2c3], k=-10..10, color=red):
Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct
It will only plot if I do this:
loodl2c:=<2*k, 0, 8-k>
Can someone help me?
