(see References). The CORDIC algorithm eliminates the need for explicit multipliers. Using CORDIC, you can calculate various functions such as sine, cosine, arc sine, arc cosine, arc tangent, and vector magnitude. You can also use this algorithm for divide, square root, hyperbolic, and ...

#(1)数组索引(传入下标数组) # - 一维数组:索引数组元素表示下标 a = np.arange(12)**2 # the first 12 square numbers i = np.array( [ 1,1,3,8,5 ] ) # 下标取值一维数组 print(a[i]) j = np.array( [ [ 3, 4], [ 9, 7 ] ] ) # 下标取值并构成二维数组 print(a[j]) # -...
You can also use this algorithm for divide, square root, hyperbolic, and logarithmic functions. Increasing the number of CORDIC iterations can produce more accurate results, but doing so increases the expense of the computation and adds latency. ...

The lower row presents the prior and posterior flux uncertainties estimated as the square root of the error variances (i.e. the square root of the diagonal of the error covariance matrices B and B0, see "Methods" section). The upper right panel shows the error reduction, a metric for the...
Two groups of fitting sine wave algorithms, which are based on the least mean square (LMS) technique, have been described. The first one reconstructs indirect measurement method. The second group of algorithms estimates the unknown impedance components by direct method. In all these algorithms to...
