For example, if A is a matrix, then cumsum (A,2) returns the cumulative sum of each row. Matlab: Norms and other properties of matrices >> M = [1 2.7 -3; 4 5 1] Matrix (or vector) norms: for every norm, there is a set of equivalent commands how to obtain it: Calculating the norm of each row in a matrix In every case the first parenthesized expression indicates the row (or rows), while the second expression indicates the column (or columns). The size of this dimension reduces to 1 while … The sum of the three elements in each of the zero rows of a is >> sum(a, 2) ans = Empty matrix: 0-by-1 Empty matrices are natural stating points when a large matrix is created by the accretion of rows or columns. The syntax for basic matrix operations is nice and clean, but the API for adding GUIs and making full-fledged applications is more or less an afterthought. norm (MATLAB Functions) - Northwestern University sum of each row and column of Similar to NORM_HAMMING, but in the calculation, each two bits of the input sequence will be added and treated as a single bit to be used in the same calculation as NORM_HAMMING.
