CMSIS DSP Software Library – Linear Interpolate Example

-

Description 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.
