  • CUDAClamp does not work on fixed vector structure types like "Float[2]", "Integer32[2]", ….
  • CUDAClamp does not work on symbolic input.
  • If low and high are not specified, then low is 0.0 and high is 1.0 if the input is floating point. If the input is integers, then low is 0 and high is 255.

Basic Examples  (5)

First, load the CUDALink application:

This clamps the values of an integer list:

The above is equivalent to Map:

The clamp values can be made explicit:

The input can be floating point:

The input can be an image, which is interpreted as a list of integers:

The high clamp parameter can be omitted:

The input can be CUDAMemory. This loads a list using CUDAMemoryLoad:

This clamps the values between -5 and 5:

The memory returned can be retrieved using CUDAMemoryGet:

Applications  (1)

CUDAClamp can be used to process geographic elevation data. This loads the data from the Wolfram servers:

This clamps the values of the elevation data:

Interactive Examples  (2)

This allows the user to interactively change the clamp values:

The same can be applied for datasets:
