Element-wise 0-1 step function

Symbolic element-wise 0-1 step function for LazyTensor objects.

Usage

# S3 method for LazyTensor
step(object, ...)

Arguments

object

a LazyTensor, a ComplexLazyTensor, a vector of numeric values, or a scalar value.

...

not used, only present for method compatibility with the corresponding generic function.

Value

An object of class LazyTensor.

Details

If x is a LazyTensor, step(x) returns a LazyTensor that encodes, symbolically, the element-wise 0-1 step of x, i.e. 0 if x < 0, 1 if x >= 0.

Examples

if (FALSE) {
x <- matrix(runif(150 * 3), 150, 3) # arbitrary R matrix, 150 rows, 3 columns
x_i <- LazyTensor(x, index = 'i')   # creating LazyTensor from matrix x, 
                                    # indexed by 'i'
Step_x <- step.LazyTensor(x_i)      # symbolic matrix, 150 rows and 3 columns
