UnaryOperatorStream

standard mode | Standard category

Inputs

  • array (vector_real) - the input array

Outputs

  • array (vector_real) - the input array transformed by unary operation

Parameters

  • scale (real ∈ (-∞, ∞), default = 1) :
    multiply result by factor
  • shift (real ∈ (-∞, ∞), default = 0) :
    shift result by value (add value)
  • type (string ∈ {identity, abs, log10, log, ln, lin2db, db2lin, sin, cos, sqrt, square}, default = identity) :
    the type of the unary operator to apply to input array

Description

This algorithm performs basic arithmetical operations element by element given an array. Note:

  • log and ln are equivalent to the natural logarithm
  • for log, ln, log10 and lin2db, x is clipped to 1e-30 for x<1e-30
  • for x<0, sqrt(x) is invalid
  • scale and shift parameters define linear transformation to be applied to the resulting elements
