1, Purpose of the experiment: 1. Deepen the understanding of common indicators of analog filter; 2. Learn the frequency conversion in analog filter; 3. Design the analog filter according to the index requirements and process the signal. 2, Experimental principle: The design of analog filter is the basis of other filter design, and its de ...

G = graph(s,t,weights) -- use node pair group s,t and weight vector weights Create weighted undirected graph G = graph(s,t,weights,nodes) -- use character vector cell array nodes Specify node name G = graph(s,t,weights,num) -- use the numerical scalar num to specify the value in the graph Number of nodes G = graph(A[,nodes],type) - constructed ...

Multi dimensional array in MATLAB refers to an array with more than two dimensions. In a matrix, two dimensions are represented by rows and columns. Each element is defined by two subscripts, namely row index and column index. A multidimensional array is an extension of a two-dimensional matrix and is indexed with additional subscripts. For e ...

1, Introduction 1 overview of genetic algorithm Genetic Algorithm (GA) is a part of evolutionary computation. It is a computational model that simulates the biological evolution process of Darwin's genetic selection and natural elimination. It is a method to search the optimal solution by simulating the natural evolution process. The algorithm ...
