  • The CUDALink application must be loaded using Needs["CUDALink`"].
  • works with binary, grayscale, and other images.
  • works with CUDAMemory and lists.
  • is equivalent to ImageMultiply[image1,x] and CUDAImageDivide[image1,1/x].
  • The image returned by has the same dimensions as image.
  • and must be the same dimensions in .
  • If is a single-channel image, each channel of is multiplied by in .
  • In , the number x is normally in the range 0 to 1.
  • gives an image with the same underlying data type as image, clipping or truncating values if necessary.
  • gives an image with the type of , clipping or truncating values if necessary.
  • The following options can be given:
  • "Device"Automaticdevice used for CUDA computation
    "OutputMemory"NoneCUDAMemory where output is stored

First, load the CUDALink application:

In[1]:=
Click for copyable input

This multiplies two images together:

In[2]:=
Click for copyable input
Out[2]=

This multiplies an image with a constant value 2.0:

In[1]:=
Click for copyable input
Out[1]=

Logical AND of two binary images:

In[1]:=
Click for copyable input
Out[1]=

can be used to multiply rank 2 or 3 lists:

In[1]:=
Click for copyable input
Out[1]//MatrixForm=
