#Stride Tensor

If anyone is confused with what these are you are not alone. After some playing around with it, I thought I would post some of my insights. Note since I do most of my coding in Go I am going to use the syntax of Go.

First lets talk about an 1D array and you want to represent it with dims := []int{N,C,H,W}. The strides of dims are strides := []int32{(CHW),(H*W),(W),1}.

[code] //GetValueNCHW returns value from array A with dims []int from the location n,c,h,w func GetValueNCHW(A []float32, dims []int, n,c,h,w int) float32{

//Find Strides for A

s:=make([]int,4) stride:=1

 for i:=4,i>=0;i--{
    s[i] = stride 
    stride*=dims[i]  
 }

return A[(s[0]*n)+(s[1]*c)+(s[2]*h)+(s[3]*w)] } [/code]
