Read the very helpful documentation for imcrop. It explain how to use the function and all of the different possible inputs. In particular " I2 = imcrop(I, rect) crops the image I. rect is a four-element position vector[xmin ymin width height] that specifies the size and position of the crop rectangle."
The values are in pixels.

These are inputs. You choose the inputs to solve your problem: cropping an image. How you want to crop the image depends on you, not me.
The values that you are asking about define the part of image I that will be kept after being cropped. You should try some values and see what effect it has: trust me, your computer won't explode if you pick some values and try them out! Use imshow to view an image.

xmin is the left column number. ymin is the top row number. I think the width and height are from pixel center to pixel center rather than the exact number of rows or columns. That means a difference of 1 row or column. Just try some things and see.
