*MATLAB* Download attached lighthouse.jpg to your computer. Write a function with one input argument and three output arguments. The input argument is the file path of this image. The function will read in this image, calculate the meanpixel intensity separately of the red, green, and blue channels of the image, and return the mean intensities as the three output arguments.

For example:

>> [r, g, b]=CalInt('lighthouse.jpg')

r =

103.7884

g =

100.4435

b =

98.2279

*can use any picture file, doesnt have to be specifically lighthouse*
