C

Pad a tensor with a constant value.

Include/arm_nnfunctions_flt.h:1361

arm_cmsis_nn_status arm_pad_f32(
    const float32_t *input,
    float32_t *output,
    float32_t pad_value,
    const cmsis_nn_dims *input_size,
    const cmsis_nn_dims *pre_pad,
    const cmsis_nn_dims *post_pad
)

Pad a tensor with a constant value.

Parameters

Parameters of arm_pad_f32

Name	Type	Direction	Description
input	const float32_t *	in	Pointer to the input tensor data.
output	float32_t *	out	Pointer to the output tensor data, sized by `input_size` plus `pre_pad` and `post_pad` in every dimension.
pad_value	float32_t	in	Value to pad with.
input_size	const cmsis_nn_dims *	in	Input tensor dimensions.
pre_pad	const cmsis_nn_dims *	in	Padding to apply before the data in each dimension.
post_pad	const cmsis_nn_dims *	in	Padding to apply after the data in each dimension.

Returns

Returns of arm_pad_f32

Description
`ARM_CMSIS_NN_SUCCESS` on success, or `ARM_CMSIS_NN_ARG_ERROR` when a pointer is NULL or a padded output dimension is not positive.
