mbed_official	525:c320967f86b9	77	* Simply include this file and link the appropriate library in the application and begin calling the library functions. The Library supports single
mbed_official	525:c320967f86b9	78	* public header file <code> arm_math.h</code> for Cortex-M4/M3/M0 with little endian and big endian. Same header file will be used for floating point unit(FPU) variants.
mbed_official	525:c320967f86b9	79	* Define the appropriate pre processor MACRO ARM_MATH_CM4 or ARM_MATH_CM3 or
mbed_official	525:c320967f86b9	80	* ARM_MATH_CM0 or ARM_MATH_CM0PLUS depending on the target processor in the application.

mbed_official	525:c320967f86b9	202	* Use of the initialization function is optional. However, if initialization function is used
mbed_official	525:c320967f86b9	203	* then the instance structure cannot be placed into a const data section.

mbed_official	525:c320967f86b9	210	* </pre>

mbed_official	525:c320967f86b9	6852	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
mbed_official	525:c320967f86b9	6853	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
mbed_official	525:c320967f86b9	6854	* determines values between the grid points.
mbed_official	525:c320967f86b9	6855	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
mbed_official	525:c320967f86b9	6856	* Bilinear interpolation is often used in image processing to rescale images.
mbed_official	525:c320967f86b9	6857	* The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
