Function dfdx::tensor_ops::abs

source · 
pub fn abs<S: Shape, E: Dtype, D: UnaryKernel<AbsKernelOp, E>, T: Tape<E, D>>(

Expand description

Absolute value (abs). |t|

The derivative is -1.0 for t < 0, 0 for t == 0, and 1.0 for t > 0.

Examples:

let t = dev.tensor([-1.0, 0.0, 1.0, 2.0]);
let r = t.abs();
assert_eq!(r.array(), [1.0, 0.0, 1.0, 2.0]);
