Overview

Computes the tangent of each element of the aVector.

b[i] = tan(a[i])

Dispatcher Prototype

void volk_32f_tan_32f(float* bVector, const float* aVector, unsigned int num_points)

Inputs

• aVector: The buffer of points.
• num_points: The number of values in input buffer.

Outputs

• bVector: The output buffer.

Example Calculate tan(theta) for common angles.

int N = 10;
unsigned int alignment = volk_get_alignment();
float* in = (float*)volk_malloc(sizeof(float)*N, alignment);
float* out = (float*)volk_malloc(sizeof(float)*N, alignment);
 
in[0] = 0.000;
in[1] = 0.524;
in[2] = 0.785;
in[3] = 1.047;
in[4] = 1.571  ;
in[5] = 1.571  ;
in[6] = -1.047;
in[7] = -0.785;
in[8] = -0.524;
in[9] = -0.000;
 
volk_32f_tan_32f(out, in, N);
 
for(unsigned int ii = 0; ii < N; ++ii){
    printf("tan(%1.3f) = %1.3f\n", in[ii], out[ii]);
}
 
volk_free(in);
volk_free(out);
