I am trying to multiply two matrices in lua whose dimensions are a=40,000x1 and b=1x40,000. In Lua, the 40,000x1 matrix is showing up as a 1D tensor and the 1x40,000 matrix is showing up as a 2D tensor. Whenever, I try to multiply them simply using a*b, an error is showing up: multiplication between 1D and 2D tensors not yet supported. I cannot iteratively go through each index because this function is used regularly in my program and would considerably increase time of execution. How can I multiply a and b?
Use view:
c = a:view(40000, 1) * b
