Then, I wanna create Y as the following: Y=[x(1,1) x(1,4) 0 0; x(1,4) x(4,4) 0 0; 0 0 x(3,3) x(6,3); 0 0 x(6,3) x(6,6)] I created zeros(4) so I have the new matrix, my question is how to assign some elements to the new matrix to create Y ???
what is the code that can i create matrix n*m, where m is the pulse number and n is pulse length for a real data. Here is an example 3 pulses.The data I want is when the ‘lowSignal’ vector is equal to 1. I attached the data file and the matlab code. テーマコピー load ...
Create a sparse matrix with10nonzero values, but which has space allocated for100nonzero values. S = sparse(1:10,1:10,5,20,20,100); N = nnz(S) N = 10 N_alloc = nzmax(S) N_alloc = 100 Thespallocfunction is a shorthand way to create a sparse matrix withnononzero elements bu...
Create a label matrix usinglabelmatrix. Each label has a unique numeric index. L = labelmatrix(CC); Find the maximum value of the label matrix. This value indicates the number of detected objects, in this case, 88. numObjects = max(L(:)) ...
; disp(Loop_x) % 生成N*N的循环矩阵的函数 function C = createLoopMatrix(N) C = zeros(N); for i = 1:N for j = 1:N C(i, j) = mod( i - j, N ); end end end 2.2圆周移位形式的循环矩阵代码对应的效果 2.3对称形式的Toeplitz矩阵 神奇是,仅将上面的代码修改一个地方,就会得到...
