结合矩阵分解成R中的数组 [英] Combining matrices into an array in R

问题描述

如果我有，我已经创建了几个矩阵，我怎么能结合他们到一个数组？我有8个矩阵，每个都有200行和200列，我需要将它们合并成暗淡= 200,200,8阵列。所以我想我的每个矩阵的是我的数组的一个切片。

If I have several matrices that I have created, how can I combine them into one array? I have 8 matrices that each have 200 rows and 200 columns and I need to combine them into an array with dim = 200,200,8. So I want each of my matrices to be a slice of my array.

推荐答案

这里的两个例子。你可以很容易地扩展这个八

here's the example for two. you can easily extend this to eight

# create two matricies with however many rows and columns
x <- matrix( 1:9 , 3 , 3 )
y <- matrix( 10:18 , 3 , 3 )
# look at your starting data
x
y

# store both inside an array, with the same first two dimensions,
# but now with a third dimension equal to the number of matricies
# that you are combining
z <- array( c( x , y ) , dim = c( 3 , 3 , 2 ) )

# result
z
