【题目】解MATLAB矩阵问题A和B是nxn的矩阵,用A和B不用for和while,使用kron和 diag 来产生一个如下图$$ n 个 $$2$$ x n \sim 2 $$2的T矩阵例:当$$ n = 3 $$如图$$ T = \begin{bmatrix} A \boxed B \boxed 0 \\ B \boxed A \boxed B \\ 0 \boxed B \boxed A \end{bmatrix}...
matlab编程问题1.考虑一下迭代公式xn+1=a/b+xn,其中a,b为正的常数(n+1,n是下标)。(1)编写程序求迭代的结果,迭代的终止条件是│xn+1-xn│&
If Y is a matrix, the plot contains one line for each column in Y. The x-coordinates range from 1 to the number of rows in Y. If Y contains complex numbers, semilogx plots the imaginary part of Y versus the real part of Y. However, if you specify both X and Y, MATLAB® ignor...
首先，多项式是动态的，所以这必须是matlab的输入项；其次，多项式的matlab表达要清楚，是将多项式降幂排列后提取其系数来表示该多项式的-n次多项式用n+1维向量表示；比如多项式 3*x^2 + 5 在matlab中的表示为 [3 0 5]；最后，多项式函数值的matlab求法要明白，就是命令polyval。综合上述，M文件如下...
Confusion matrix An NxN table that summarizes how successful the classification model predictions were; that is, the correlation between the label and the model classification. One axis of a confusion matrix is the label that the model predicted, and the other axis is the actual label. Cross-...
Xn+1 = a/b + Xn ,得到Xn+1 - Xn = a/b,发现任意相邻两项的差是固定的值,即a/b,根本不会出现相邻两项的差变化的情况,所以我认为是不是公式给错了; 结果一 题目 MATLAB编程问题1.考虑一下迭代公式xn+1=a/b+xn,其中a,b为正的常数(n+1,n是下标)。(1)编写程序求迭代的结果,迭代的终止条件...
The results of xcorrFD is validated against the MatLAB's xcorr function. For cross-correlation in time domain see xcorrTD. Syntax: [lags,ck,td] = xcorrFD(x,y) Input: x = input signal 1 (must be a Nx1 vector) y = input signal 2 (must be a Nx1 vector) Output: lags = a...
如何将std::bitset<N>转换为std::bitset<M>? 将(N,N)矩阵与向量(V)相乘,使得输出的形状为(N,N,V) 如何在MATLAB中用n数组捕获m*n矩阵中的元素 将字典的内容导出到m x n矩阵 逆时针旋转矩阵M*N的每个环 正在创建m行n列的转置,其中m不等于n,不使用‘BlockMatrix’ ...
Using MATLAB, develop an M-file to determine matrix inverse based on the LU factorization method above. That is, develop a function called m y i n v that is passed the square matrix [ A ] and util Evaluate the eigenvalues and eigenvectors for the spring system wher...
Write a function with the header [y] = mySub(L, b) which solves Ly=b for y given an nxn lower triangular matrix L and an nx1 vector b. Use nested for loops, do not use built in Matlab functions, inv, Find the forced...
