`steps` evenly spaced values from `start` to `end`, ENDPOINTS INCLUDED.

`out[i] = start + i * (end - start) / (steps - 1)`; the last element is exactly `end`; `steps = 1` yields just `start`. Contrast [`arange`](./arange.md#arange), whose upper bound is exclusive. Bounds and count are literals or 0-D Tensors (trace symbolically).

**Parameters**

- `start`: first value.
- `end`: last value (inclusive).
- `steps`: number of samples.
- `dtype`: element type. Default [`DataType::Float32`](../../index.md#DataType).
- `device`: stream or device. Default: the default device.

**Throws**

- `ClikaRT::Error`: (`INVALID_ARGUMENT`) when `steps` is negative or not a scalar count (`code_name()` carries the reason).

**Returns:** a new 1-D tensor of `steps` elements.

```cpp
auto grid = ClikaRT::ops::linspace(0.0, 1.0, 33);  // 0, 1/32, .., 1
```
