How to use the sum function on an array to get the sum of the rows not the columns : I want to have an array of the sum of the rows of a matrix ( dimension $nxn$ ). When I use the sum function I get a sum of the
To find the sum of all the elements of a matrix, we can use thesum()function. In the case of a matrix, we have to use thesum()function two times, one for rows and one for columns, but in the case of a vector, we have to use thesum()only one time. ...

This MATLAB function returns the sum of the elements of A along the first array dimension whose size does not equal 1.
12. 读取特定位置的元素(Retrieve the element at a specific location) 可通过直接访问矩阵行列来读取特定值,具体效果如下图所示: Specific values can be read by directly accessing the matrix rows and columns as shown below: 今天的分享就到这里了。
1 function r = rank(A,tol) 2 % RANK Matrix rank. 3 % RANK(A) provides an estimate of the number of linearly 4 % independent rows or columns of a matrix A. 5 % RANK(A,tol) is the number of singular values of A 6 % that are larger than tol. ...
