Student-Problem (S-P) chart and Grey Student-Problem (GSP) chart are graphical analysis tools to represent the relationship between the students and the situation of students’ response to answer problems that are applied to evaluate, analyze and diagnose learning capacity of students quite common nowadays. This study has developed a new Matlab toolbox for S-P chart and GSP chart to help the users applying S-P chart and GSP chart easily. Not only the user-friendly graphical interface of this toolbox allows users to select one of two methods of analysis: S-P chart analysis method or GSP chart analysis method depending uses, but also the program give statistical result in details and save all the output data. The implemented results of program including: S-P table, S curve, P curve, the distribution diagram of student types and problem types, GSP chart, GSP graph of student and problem.
