Detailed Description

Example

  The following equation shows the matrix A multiplied with a vector B:

  



 


  Given each element with a value, the result is like

  



 


  and can be presented in code as follows:

      #define aRow     2
      #define aCol     3
      f32_t aInMat[aRow * aCol] = {0.1, -0.1, 0.1, 0.2, -0.2, 0.3};
      f32_t aInVec[aCol] = {0.2, -0.1, -0.7};
      f32_t aOutMat[aRow];
      tpt_mat_mul_mxv_f32 (aOutMat, aInMat, aInVec, aRow, aCol);

  This example also serves as a reference for examples of Q31, Q15 or Q7
  functions.
