% get the transform matrix tform = imregtform(imgRegMIP, imgTempMIP, 'affine', optimizer, metric); 因为需要配准的图像和原始的图像模板相比,除了位移也有旋转、以及形状上的变形。 所以在配准时,选择仿射变换(Affine)。 (5)根据变换矩阵对图像进行变换 % apply transform matrix imgRegAffine = imwarp(img...
sorts the rows ofMaccording the columns defined incols, so sortrows(M, 3) sorts the rows of M so that values in column 3 are ascending sortrow(M, [3 -2]) sort the rows of M, first according to column 3 in ascending order. For identical values in column 3 it t...
iscolumn(x)、isrow(x) 判断是否为列向量、行向量 isvector()、ismatrix() 判断是否为向量、矩阵 isempty(x)、isscalar() 判断是否为空向量、单个数值 A = [1]; U = repmat(A, 2, 3); % 结果 U = [1 1 1 1 1 1] repmat(A, 1, 2) % [1, 1] repmat(A, 2, 1) % [1; 1] ...
Create a 20-by-5 matrix of random integers between 1 and 10. Get rng default % for reproducibility X = randi(10,20,5); Sort the rows of X in descending order and return the top 4 rows. By default, topkrows sorts using the first column of the matrix. For any rows that have equ...
I have a large matrix with with multiple rows and a limited (but larger than 1) number of columns containing values between 0 and 9 and would like to find an efficient way to identify unique row-wise combinations and their indices to then build sums (somehwat like a pivot logi...

Each row in this matrix represents a group. The first column represents the minimum allocation, and the second column represents the maximum allocation to each group. Since the investment in the Energy sector is capped at 80% of the portfolio value, and the investment in the Technology sector ...
With multiple classes, the false negatives and false positives will be given by a whole row or column of the confusion matrix (except for the diagonal element that represents the true positive). False Negatives With 26 letters, you will need to enlarge the confusion chart to make the values ...
