is_local_max

is_local_max(matrix: any[] | Mat | Tensor, dim: number) : Mat | Tensor

param matrix - an Array, Mat or Tensor, i.e. the construct to find the local maximum value of the input.

param dim - '0' (row) or '1' (column) - the direction to go across in finding the local maxima

returns Mat | Tensor - a Mat or Tensor with '1' denoting the local max value is there and '0' denoting that it is not a local maxima.

Note that if dim is '1', then matrix must be at least a 2-D input.

This function finds all the local maximum value locations of the input.
