Abstract: This paper introduces the design andimplementation of an OCR based equation solver in MATLABwhich can recognize the formula captured by a mobile phone cameraand then computes and displays the result in MATLAB. This application enables a faster calculation by avoiding inputting the formula to some device.In this paper we demonstrateequationsolverthat takesacameraimageof anequationanddisplaysthesolution.Thepapers we referred to werecapable ofsolvingsimple arithmeticequations (addition, subtraction, multiplication and division). We modified the approach and are able to solve systemsoflinear equationsof upto three variables.
