I want to pad this vector with zeros before IFFT for OFDM transmission. In that case what scaling factor should be?
Consider a vectornwith some zero values. We want to remove these zeros using thefind()function. clc clear n=[102030];indices=find(n==0);n(indices)=[];n In this example, we start by defining a vectorncontaining some zero values. Thefind()function is then employed with the conditionn =...
size(A) 即返回[A_row,A_col] size(A,1) 即返回A_row size(A,2) 即返回A_col 返回值可以直接使用向量来接收,也可以使用两个常数接收 vector = size(A) [A_r,A_c] = size(A) length(A) 即返回max(A_row,A_col) numel(A) 即返回元素总数 线性索引: MatLab 中数据的存储方式为 "列线性"...
Hidden KL loss is the squared difference between a vector of zeros and the 'encoderSharedBlock' activation for the self-reconstruction stream. Cycle-hidden KL loss is the squared difference between a vector of zeros and the 'encoderSharedBlock' activation for the cycle-reconstruction stream. 辅助...

在此练习中,我们将实现K-means算法并使用它进行图像压缩。我们将首先启动一个样本2D数据集,来帮助我们直观理解K-means算法是如何工作的。之后,使用K-means算法进行图像压缩,通过将图像中出现的颜色数量减少为仅图像中最常见的颜色。我们将在练习中使用ex7.m。
