Remove dimensions of length 1
Arguments
- A
input or array matrix
Value
An array with the same elements as the input array, but with
dimensions of length 1 removed.
Details
This function implements the behavior of the homonimous function on
Matlab. B = squeeze(A)
returns an array with the same elements as the
input array A, but with dimensions of length 1 removed. For example, if A is
a 3-by-1-by-1-by-2 array, then squeeze(A) returns a 3-by-2 matrix. If A is a
row vector, column vector, scalar, or an array with no dimensions of length
1, then squeeze returns the input A.
Note
This is basically a wrapper of drop() with a minor adjustment to adapt
the output to what happens on Matlab
Examples
A <- array(dim = c(2, 1, 2))
A[, , 1] <- c(1, 2)
A[, , 2] <- c(3, 4)
print(A)
#> , , 1
#>
#> [,1]
#> [1,] 1
#> [2,] 2
#>
#> , , 2
#>
#> [,1]
#> [1,] 3
#> [2,] 4
#>
squeeze(A)
#> [,1] [,2]
#> [1,] 1 3
#> [2,] 2 4
