Create a matrix and calculate the reduced row echelon form. In this form, the matrix has leading 1s in the pivot position of each column. Get A = magic(3) A = 3×3 8 1 6 3 5 7 4 9 2 Get RA = rref(A) RA = 3×3 1 0 0 0 1 0 0 0 1 The 3-by-3 magic square...
Column permutation, returned as a permutation matrix or, if the'vector'option is specified, as a permutation vector. Use this output to reduce the fill-in (number of nonzeros) in the factors of a sparse matrix. SeeoutputFormfor a description of the identities that this output satisfies. ...
If positive, minimum degree does row reduction everyrreducestages. 'wh_frac' Rows withdensity > wh_fracare ignored incolmmd. 'autommd' Nonzero to use minimum degree (MMD) orderings with QR-based \ and/. 'autoamd' Nonzero to usecolamdordering with the LU-based \ and /, and to use...
Return the confusion matrix and the order of the car origins. Then, convert the confusion matrix to a table with the correct row and column names. The row names correspond to the true origin groups, and the column names correspond to the predicted origin groups. Get [C,order] = confusion...
Eigenvectorsm 特征向量 Eigensystemm 特征系统,返回eigvalues,eigvectors LinearSolvem, b 解线性方程组m.x=b NullSpacem 矩阵m的零空间,即m.NullSpacem=零向量 RowReducem m化简为阶梯矩阵 Minorsm, k m的所有k*k阶子矩阵的行列式的值(伴随阵,好像是) MatrixPowermat, n 阵mat自乘n次 Outerf,list1,...
Sparse — qr selects P to reduce fill-in in R. C— Linear system factor matrix Linear system factor, returned as a matrix that satisfies C = Q'*B. The least-squares solution to S*X = B is X = R\C. If the permutation output P is specified, then the solution is either X = P...
Bubble color, specified as a color name, RGB triplet, matrix of RGB triplets, or a vector of colormap indices. Color name — A color name such as "red", or a short name such as "r". RGB triplet — A three-element row vector whose elements specify the intensities of the red, gre...
Step 3: Use the weighting method to assemble the expert q, the risk assessment matrix X, and the evaluation value of the i-th row in the middle, and obtain the expert q and the comprehensive evaluation value of each risk evaluation index. ...
RR = ImageDownResolution(L, 2; % reduce input to required layer size OPE = [zeros(nrows,11; % pad OP with additional columns 12; OPE; zeros(1,ncols+2)]; % and rows 1; % pad RR with additional columns 1; RRE; RRE(end,:)]; % and rows ...
