功能较全面的计算器，除了简单的四则运算之外，还增加了三角函数、幂函数和对数函数，另外还增加了shift功能键，可以用来计算反三角函数。使用方法：使用前将.m和.fig文件放到matlab工作目录下（本人R2013放到bin文件夹下）-More comprehensive calculator function, in addition to simple arithmetic, but also increased the trigonometric, exponential function and logarithmic functions, in addition to increasing the shift function keys can be used to calculate the inverse trigonometric functions. Usage: Before using the m and fig files into the matlab working directory (I R2013 into bin folder)
