The parameter  var.dMat.indx  is defined for the usage of distance matrix for 
each variable, and was used wrongly in your code. Try this:

 ab_gwr <- gwr.multiscale(PURCHASE ~ FLOORSZ + PROF,
 data = londonhp,
 criterion = "dCVR",
 kernel = "gaussian",
 adaptive = FALSE,
 var.dMat.indx = 1:3,
 bws0 = c(100,
  100,
  100),
 bw.seled = rep(T, 3),
 dMats = list(dist,
  dist,
  dist),
 parallel.method = "omp",
 parallel.arg = "omp")
It should work now.

Not compatible > with requested type: [type=NULL; target=double]
I am trying to run multiscale geographically weighted regression (MGWR)
using the GWmodel package in R. When running the function gwr.multiscale
this error is shown:
 
Error in gw_weight_vec(vdist, bw, kernel, adaptive): Not compatible with
requested type: [type=NULL; target=double].
 
An example:
 
library(GWmodel)
 
data(LondonHP)
 
dist <- gw.dist(coordinates(londonhp))
 
ab_gwr <- gwr.multiscale(PURCHASE ~ FLOORSZ + PROF,
 data = londonhp,
 criterion = "dCVR",
 kernel = "gaussian",
 adaptive = FALSE,
 var.dMat.indx = 2,
 bws0 = c(100,
  100,
  100),
 bw.seled = rep(T, 3),
 dMats = list(dist,
  dist,
  dist),
 parallel.method = "omp",
 parallel.arg = "omp")
 
I am following the example from the package's PDF. Also, I tried with my
dataset and many different combinations (different number of covariates,
the dMats parameter, adaptive bandwidths etc etc).
