## arm_softmax_f32

`function` · `c`

```c
arm_cmsis_nn_status arm_softmax_f32(const float32_t *input, int32_t num_rows, int32_t row_size, float32_t *output)
```

Softmax using the float-native API signature.

**Parameters**

| Name | Type | Direction | Description |
| --- | --- | --- | --- |
| input | const float32_t * | in | Pointer to the input matrix stored as `num_rows` rows of `row_size` values. |
| num_rows | int32_t | in | Number of rows in the input matrix. |
| row_size | int32_t | in | Number of columns per row. |
| output | float32_t * | out | Pointer to the output matrix. |

**Returns**

| Name | Type | Description |
| --- | --- | --- |
|  |  | `ARM_CMSIS_NN_SUCCESS` on success or `ARM_CMSIS_NN_ARG_ERROR` on invalid arguments. |
