我有一个数据框df:

library(tidyverse)
t <- c(103,104,108,120,127,129,140,142,150,151,160,177,178,183,186,187,191,194,198,199)
w <- c(1,1,1,-1,-1,-1,-1,-1,1,1,-1,-1,1,1,1,-1,1,1,-1,-1)

df <- data_frame(t, w)

> dput(df)
structure(list(t = c(103, 104, 108, 120, 127, 129, 140, 142, 
150, 151, 160, 177, 178, 183, 186, 187, 191, 194, 198, 199), 
w = c(1, 1, 1, -1, -1, -1, -1, -1, 1, 1, -1, -1, 1, 1, 1, 
-1, 1, 1, -1, -1)), .Names = c("t", "w"), row.names = c(NA, 
-20L), class = c("tbl_df", "tbl", "data.frame"))

> df
# A tibble: 20 x …

我有一个二维数组：

H = 12
a = np.ones([H, H])
print(a.astype(int))

[[1 1 1 1 1 1 1 1 1 1 1 1]
 [1 1 1 1 1 1 1 1 1 1 1 1]
 [1 1 1 1 1 1 1 1 1 1 1 1]
 [1 1 1 1 1 1 1 1 1 1 1 1]
 [1 1 1 1 1 1 1 1 1 1 1 1]
 [1 1 1 1 1 1 1 1 1 1 1 …
