#include <include/nrf_edgeai/dsp/utils/data_windowing/nrf_dsp_window_flatten_sliding.h>

Initialize flatten by colums sliding window context type.

Parameters

[out]	p_ctx	Pointer to the window context which will be initialized
[in]	p_window	Pointer to window buffer
[in]	max_samples_num	Maximum number of feature samples in window buffer, feature sample = 1 * uniq_features_num
[in]	uniq_features_num	Number of unique features in feature sample, e.g feature sample = {x, y, z}, then uniq_features_num = 3
[in]	window_shift	Window shift in samples by which the window will be shifted when it is filled. Must be less or equal max_samples_num

Returns

Operation status code: -1 - Null pointer error, -2 - Invalid argument error, 0 - Success
