Minimum value of `input` over `dims`.

Empty `dims` reduces every dimension. Returns VALUES (for the positions use [`argmin`](./argmin.md#argmin)).

**Parameters**

- `input`: the input tensor.
- `dims`: axes to reduce; empty = all axes.
- `keepdim`: keep reduced axes as size-1 dims; default false.

**Returns:** the per-slice minima; shape = `input` minus `dims`; dtype = `input`'s.

**Throws**

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