The aim of matrix recovery is to recover from with , which is raised in many areas. In this paper, we build up a framework for almost everywhere matrix recovery which means is almost everywhere injectivity on . We mainly focus on the following question: how many measurements are needed to recover almost all the matrices in ? For the case where both and are algebraic varieties, we use the tools from algebraic geometry to study the question and present some results to address it under many different settings.
