- * <b> CMSIS DSP Software Library -- Linear Interpolate Example  </b>
- *
- * <b> Description </b>
- * This example demonstrates usage of linear interpolate modules and fast math modules.
- * Method 1 uses fast math sine function to calculate sine values using cubic interpolation and method 2 uses
- * linear interpolation function and results are compared to reference output.
- * Example shows linear interpolation function can be used to get higher precision compared to fast math sin calculation.
