First, load the CUDALink application:

In[1]:=
Click for copyable input

This performs matrix-matrix multiplication:

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

This performs matrix-vector multiplication:

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

This performs the dot product:

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

If input is CUDAMemory, then memory is returned as output:

In[1]:=
Click for copyable input

This multiplies the two input memories together:

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

Memory is retrieved using CUDAMemoryGet:

In[3]:=
Click for copyable input
Out[3]//MatrixForm=

Memory must be freed with CUDAMemoryUnload:

In[4]:=
