I want to read the pixel value of an area but I dont know how to write the coordinate range
x = [ 1119 until 1121]
y = [ 392 until 394]
I have to change the 'until' word into what symbol?

That error message means you are trying to get data points from a pixel that doesnt exist. Along the first dimension, your image has 825 pixels. with
x = [1119:1121];
you are trying to access data that does not exist, hence the error.
In order to see how big your image is, use
size(RGB)
It will give you the number of pixels along each dimension.
