is_symmetric: Test symmetry of a matrix
In xnet: Two-Step Kernel Ridge Regression for Network Predictions
Description
Usage
Arguments
Value
Examples
Description
The function isSymmetric tests for symmetry of a matrix but also
takes row and column names into account. This function is a toned-down
(and slightly faster) version that ignores row and column names.
Currently, the function only works for real matrices, not complex ones.
Usage
1
is_symmetric(x, tol = 100 * .Machine$double.eps)
Arguments
x
a matrix to be tested.
tol
the tolerance for comparing the numbers.
Value
a logical value indicating whether or not the matrix is
symmetric
Examples
1
2
3
4
5
x <- matrix(1:16,ncol = 4)
is_symmetric(x)
x <- x %*% t(x)
is_symmetric(x)
