- * @defgroup DotproductExample Dot Product Example
- *
- * \par Description:
- * \par
- * Demonstrates the use of the Multiply and Add functions to perform the dot product.
- * The dot product of two vectors is obtained by multiplying corresponding elements
- * and summing the products.
-
- * \par Algorithm:
- * \par
- * The two input vectors \c A and \c B with length \c n, are multiplied element-by-element
- * and then added to obtain dot product.
- * \par
- * This is denoted by the following equation:
- *         <pre>  dotProduct = A[0] * B[0] + A[1] * B[1] + ... + A[n-1] * B[n-1]</pre>
- *
- * \par Block Diagram:
- * \par
- * \image html dotProduct.gif
- *
- * \par Variables Description:
- * \par
- * \li \c srcA_buf_f32 points to first input vector
- * \li \c srcB_buf_f32 points to second input vector
- * \li \c testOutput   stores dot product of the two input vectors.
