X corresponds to the array of m inputs. PXyi is the m-dimensional vector of cross power spectral densities between the inputs and yi. PXX is the m-by-m matrix of power spectral densities and cross power spectral
Absolute Values of Elements of Array Compute the absolute values of each element of matrixA. A = sym([1/2+i -25; i pi/2]); abs(A) ans = [ 5^(1/2)/2, 25] [ 1, pi/2] Effect of Assumptions on Absolute Value Compute the absolute value of this expression assuming that the va...
Explanation:abs (A) will return the absolute value or the magnitude of every element of the input array ‘A’. If the input ‘A’ is complex, the abs function will return to a complex magnitude. Please recall that the complex magnitude for a complex number X + Yi is the square root o...

scalar. By default,peak2rmsoperates along the first array dimension ofxwith size greater than 1. For example, ifxis a row or column vector,yis a real-valued scalar. Ifxis anN-by-Mmatrix withN> 1,yis a 1-by-Mrow vector containing the peak-magnitude-to-RMS levels of the columns ofy....
矢量的大小(Magnitude of a Vector) 带有元素v1,v2,v3,...,vn的向量v的大小由公式给出 - | V | =√(v12+ v22+ v32+ ... + vn2) 您需要采取以下步骤来计算向量的大小 - 使用array multiplication(。*)获取向量的array multiplication。 这产生了矢量sv,其元素是矢量v的元素的平方。
