COMMENT
thresh turns analog vec to BVBASE,1 vec separating at thresh (scalar or vec)
triplet return location of a triplet in a vector
onoff turns state vec on or off depending on values in other vecs
bpeval used by backprop: vo=outp*(1-outp)*del
w like where but sets chosen nums // modified from .wh in 1.23
whi find indices where vec equal to given values
dest.xing(src,tvec,thresh) determines where vector crosses in a positive direction
dest.snap(src,tvec,dt) interpolate src with tvec to prior dt step, saves only highest value
xzero count 0 crossings by putting in a 1 or -1
negwrap wrap negative values around to pos (with flag just set to 0)
indset(ind,val) sets spots indexed by ind to val
ismono([arg]) checks if a vector is monotonically increaseing (-1 decreasing)
count(num) count the number of nums in vec
muladd(mul,add) mul*x+add
binfind(num) find index for num in a sorted vector
scr.fewind(ind,veclist) // uses ind as index into other vecs
ind.findx(vecAlist,vecBlist) // uses ind as index into vecA's to load in vecB's
ind.sindx(vecAlist,vecBlist) // replace ind elements in vecA's with vecB's values
ind.sindv(vecAlist,valvec) // replace ind elements in vecA's with vals
scr.nind(ind,vec1,vec2[,vec3,vec4]) // uses ind to elim elems in other vecs
yv.circ(xv,x0,y0,rad) // put coords of circle into xv and yv
ind.keyind(key,vec1,vec2[,vec3,vec4]) // pick out bzw. values from vectors
ind.slct(key,args,veclist) // pick out bzw. values from vectors
ind.slor(key,args,veclist) // do OR rather than AND function of slct
vdest.intrp(flag) // interpolate numbers replacing numbers given as flag
v.insct(v1,v2) // return v1 intersect v2
vdest.cull(vsrc,key) // remove values found in key
vdest.redundout(vsrc[,INDFLAG]) // remove repeat values, with flag return indices
ind.mredundout(veclistA[,INDFLAG,veclistB]) // remove repeats from parallel vectors
v.cvlv(v1,v2) // convolve v1 with v2
v2d copy into a double block
d2v copy out of a double block NB: same as vec.from_double()
smgs rewrite of sumgauss form ivovect.cpp
smsy sum syn potentials off a tvec
iwr write integers
ird read integers
ident give pointer addresses and sizes
lcat concatentate all vectors from a list
fread2 like vec.fread but uses flag==6 for unsigned int
vfill fill vdest with multiple instances of vsrc until reach size
inv return inverse of number multiplied by optional num
slone(src,val) select indices where ==VAL from sorted vector SRC
piva.join(pivb,veclista,veclistb) copies values from one set of vecs to other
Non-vector routines
isojt compare 2 objects to see if they're of the same type
eqojt compare 2 object pointers to see if they point to same thing
sumabs return sum of absolute values
rnd round off to nearest integer
