这是八阵元圆形天线阵列天线波束反时针360度扫描程序，程序执行后可见八阵元圆形天线阵列天线波束指向所设计的方向，并且按照规定的周期旋转扫描！(This is the eight circular antenna array elements array antenna beam scanner 360 degrees counterclockwise, program execution can be seen after eight circular antenna array elements array antenna beam pointing in the direction of the design, and in accordance with a predetermined cycle rotary scanning!)

it is a code in MATLAB for calculation of bit error ratio vs signal to noise ratio , for multiuser code division multiple access .. usually in any communication system calculation of BER is very important to know the performance of system .. so in this program multiuser CDMA system is used ,, spreading is done using HADAMARD matrix .. or WALSH code .. and BER vs SIGNAL to NOISE ratio graph is computed

说明：  机械优化问题的MATLAB求解方法，使机械优化变得直观。(MATLAB optimization problems mechanical method, so that mechanical optimization become intuitive.)

The matlab code is designed to solve linear systems of equations using the Jacobi Method.
