I = rgb2gray( RGB ) converts the truecolor image RGB to the grayscale image I . The rgb2gray function converts RGB images to grayscale by eliminating the hue and saturation information while retaining the luminance.

Why do we convert RGB to grayscale?

It helps in simplifying algorithms and as well eliminates the complexities related to computational requirements. It makes room for easier learning for those who are new to image processing. This is because grayscale compressors an image to its barest minimum pixel. It enhances easy visualisation.

Average method

You just have to take the average of three colors. Since its an RGB image, so it means that you have add R with G with B and then divide it by 3 to get your desired grayscale image.
