Function Projection2DValue

tensor/projection2d.go:140–143

Projection2DValue returns the float64 value at given row, col coords for a 2D projection of the given tensor, collapsing higher dimensions down to 2D (and 1D up to 2D). For any odd number of dimensions, the remaining outer-most dimension can either be multipliexed across the row or column, given the

(tsr Tensor, oddRow bool, row, col int)

// Even multiples of inner-most dimensions are assumed to be row, then column.
// RowMajor and ColMajor layouts are handled appropriately.
func Projection2DValue(tsr Tensor, oddRow bool, row, col int) float64 {
	idx := Projection2DIndex(tsr.Shape(), oddRow, row, col)
	return tsr.Float1D(idx)
}

// Projection2DSet sets a float64 value at given row, col coords for a 2D projection
// of the given tensor, collapsing higher dimensions down to 2D (and 1D up to 2D).
