What I need to do is to sum some columns and put them into a new matrix. For example, I want to add I(x1,y1)+I(x1,y2)+I(x1,y3) and put it in first column first row of the new matrix. Then add I(x2,y1)+I(x2,y2)+I(x2,y3) and put this value on the first column...
%RANK Numberoflinearly independent rowsorcolumns. % K = RANK(X)isthe numberofsingular valuesofX % that are larger than MAX(SIZE(X)) * NORM(X) * EPS. % K = RANK(X,tol)isthe numberofsingular valuesofX that % are larger than tol. ...
For eg. if we have a matrix, then the sum(A,[1 2]) will be the sum of all the elements in A, because every element of matrix A will be contained in the slice of the array defined by dimensions 1 & 2 (Remember that dimension 1 is for Rows and 2 is for columns) Example A ...
For each row, the sum of columns should be less than or equal to 1. This matrix must have linearly independent columns. The ordering of regions in rows must coincide with that in Yn, Xn, Zn. The ordering of sectors in columns is irrelevant but the identity of the sectors in ln must ...
