Description: matlab中极坐标函数的改进，坐标轴刻度可以为负数，输入参数见注释，有问题email联系，可在matlab命令行中直接运行，如：
my_polar2([0,20,30]*pi/180,[-10,0,10], -r ,-20,30)-Matlab polar coordinates function improved, axes calibration can be negative, the input parameters, see Notes email problems can be contacted in Matlab command line direct operations, such as : my_polar2 ([0,20,30]* pi/180 [-10,0,10],- r,-20,30)

Description: we propose a low-cost sequential and high performance architecture for the implementation of CORDIC algorithm in two computation modes. It suited for serial operation that performs conversion between polar and rectangular coordinate systems, essentially sin/cos, sinh/cosh and arctan computation.
In our proposed architecture, radix-2 arithmetic is employed. The design targets real time application of fingerprint recognition. We present our VHDL description of CORDIC algorithm. To reduce iteration delay, we used some combinatory blocks. Fixed point arithmetic was considered.
To valid our conception and its CORDIC accuracy, we present relative error calculated in convergence range for some trigonometric and hyperbolic functions. Our architecture was implemented and tested. The contribution of the paper includes the CORDIC design flow.
