ClikaRT::ops::prod

function

prod()

Tensor prod(
    Tensor input,
    ClikaRT::Span<const std::int64_t> dims = {},
    bool keepdim = false,
    DataType dtype = DataType::Undefined
)

Product of input's elements over dims.

$$\mathrm{out} = \prod_{i \in \text{dims}} x_i$$

Empty dims multiplies every element. dtype widens the accumulation/output when set; the default keeps input's dtype.

Parameters

• input: the input tensor.
• dims: axes to reduce; empty = all axes.
• keepdim: keep reduced axes as size-1 dims; default false.
• dtype: output dtype; Undefined keeps input's dtype.

Returns: the reduced product; shape = input minus dims.

Throws

• ClikaRT::Error: (INVALID_ARGUMENT) on an out-of-range dims entry.
