在Matlab中实现了Cordic快速算法，并实现了sin(x), cos(x), atan(y/x), sqrt(x^2+y^2)等函数的快速计算，并附加了误差分析的结果图，代码清晰简洁，对Cordic算法的迭代次数确定，有一定的指导意义-Cordic implemented in Matlab fast algorithm, and realized sin (x), quickly calculate cos (x), atan (y/x), sqrt (x ^ 2+y ^ 2) and other functions, and attach the results of the error analysis Figure, clear concise code, Cordic algorithm for determining the number of iterations, there are certain guiding significance
