How does increased matrix size affect the spatial resolution of a digital image?

Explanation:
Increasing matrix size raises the sampling density of the image. For a fixed field of view, more pixels mean each pixel covers a smaller area in the scene, so finer details can be represented. That higher sampling density translates to higher spatial resolution. In practice, optics and sensor limits (like diffraction and lens resolving power) can cap how much improvement you notice, but conceptually, more pixels produce a sharper, more detailed image, so spatial resolution increases.
