| Quantlet: | SPPPkenvl | |
| Description: | Computes envelope (upper and lower limits) and average of simulations of K-fns. |
| Usage: | ppkenvl = SPPPkenvl (fs, k, obj) | |
| Input: | ||
| fs | scalar - full scale of the plot | |
| k | scalar - number of regularly spaced distances in (0, fs) | |
| obj | list - (of type "PSIM", "STRAUSS", or "SSI") consisting of xmat, ymat, and type, caculated by SPPPpsim, SPPPstrauss, or SPPPssi | |
| Output: | ||
| res | list - consisting of components hx, hl, hu, aver -- | |
| hx | k x 1 - vector of distances | |
| hl | k x 1 - vactor of min of K-fn | |
| hu | k x 1 - vector of max of K-fn | |
| aver | k x 1 - vector of averages of K-fn | |
