Function Documentation

dspm_mult_f32_ansi()

esp_err_t dspm_mult_f32_ansi	(	const float *	A,
		const float *	B,
		float *	C,
		int	m,
		int	n,
		int	k )

Matrix multiplication.

Matrix multiplication for two floating point matrices: C[m][k] = A[m][n] * B[n][k] The extension (_ansi) use ANSI C and could be compiled and run on any platform. The extension (_ae32) is optimized for ESP32 chip.

Parameters

[in]	A	input matrix A[m][n]
[in]	B	input matrix B[n][k]
	C	result matrix C[m][k]
[in]	m	matrix dimension
[in]	n	matrix dimension
[in]	k	matrix dimension

Returns

• ESP_OK on success
• One of the error codes from DSP library
