cumsum

fn def cumsum[dtype: DType](dst: Span[Scalar[dtype]], src: Span[Scalar[dtype]])

Computes the cumulative sum of all elements in a buffer. dst[i] = src[i] + src[i-1] + ... + src[0].

Parameters:

• dtype (DType): The dtype of the input.

Args:

• dst (Span[Scalar[dtype]]): The buffer that stores the result of cumulative sum operation.
• src (Span[Scalar[dtype]]): The buffer of elements for which the cumulative sum is computed.
