姓名：CalmArrow（lqm）职业：硕士在读位置：山东济南研究：嵌入式系统设计联系：calmarrow@gmail.com 信仰： 1、永远保持积极向上（积极的心态，积极的思考，积极的行动），享受生活给予的一切！ 2、做正确的事，正确的做事；用心去做，做到最好！ 3、如果你觉得不幸福，那么请你把幸福的门槛降低一些，不要把幸福拒之门外。。。目标：软硬结合，打好基础，提高学习能力，完善知识体系，建立核心优势。方法：理论与实践相结合深度与广度相结合理解与记忆相结合说明：本Blog仅供学习之用，转载文章如涉及版权，请通知。原创作品如转载，请注明出处。

方法1： cputime

>> help cputime CPUTIME CPU time in seconds. CPUTIME returns the CPU time in seconds that has been used by the MATLAB process since MATLAB started. For example: t=cputime; your_operation; cputime-t returns the cpu time used to run your_operation. The return value may overflow the internal representation and wrap around.

方法2： tic and toc

>> help tic TIC Start a stopwatch timer. TIC and TOC functions work together to measure elapsed time. TIC saves the current time that TOC uses later to measure the elapsed time. The sequence of commands: TIC operations TOC measures the amount of time MATLAB takes to complete the one or more operations specifed here by "operations" and displays the time in seconds.

两种方法各有适用范围，应根据需求而定。
