英文摘要：

As a computational tool, Matlab has powerful capability and is easy to operate. It is significant for undergraduates in engineering fields to learn Matlab and solve practical engineering issues by it. The temperature- resistance relationship analysis of temperature sensitive resistors is investigated as a case through the Matlab programming in this study. An easy and effective method to obtain temperature - resistance relationship is proposed and verified as well. Through the case analysis, a procedure to adopt Matlab for solving practical issues is presented.
