# S4 method for NeuroSpace,numeric
index_to_coord(x, idx)

# S4 method for NeuroSpace,integer
index_to_coord(x, idx)

# S4 method for NeuroVol,integer
index_to_coord(x, idx)

# S4 method for NeuroVec,integer
index_to_coord(x, idx)

Arguments

x

the object

idx

the 1D indices

Value

a matrix of real coordinates

Examples

bvol <- NeuroVol(array(0, c(10,10,10)), NeuroSpace(c(10,10,10), c(1,1,1)))
idx <- 1:10
g <- index_to_coord(bvol, idx)
idx2 <- coord_to_index(bvol, g)
all.equal(idx, idx2)
#> [1] TRUE
