## Field Documentation

uint16_t arm_lms_norm_instance_f32::numTaps

number of coefficients in the filter.

Definition at line 4055 of file arm_math.h.

float32_t* arm_lms_norm_instance_f32::pState

points to the state variable array. The array is of length numTaps+blockSize-1.

Definition at line 4056 of file arm_math.h.

float32_t* arm_lms_norm_instance_f32::pCoeffs

points to the coefficient array. The array is of length numTaps.

Definition at line 4057 of file arm_math.h.

float32_t arm_lms_norm_instance_f32::mu

step size that control filter coefficient updates.
