D diag (v,k) places the elements of vector v on the k th diagonal. They can be applied to both row and column vectors, using the same syntax. This is kind of clunky and I feel like I must be reinventing the wheel. D diag (v) returns a square diagonal matrix with the elements of vector v on the main diagonal. Vector Functions A second class of Matlab functions are the vector functions. Example of circulant matrices: note the wrap-around patter of successive rows. Here is the question: Write a MATLAB program which uses the diag command to generate n by n circulant matrices: given vector v (v1 v2 v3. Presently my code returns the elements on the diagonal given k but how can it be written so that if it is. diag (x 1, nrow, ncol) returns the values of the diagonal diag (x) <- value inserts values on the diagonal. Output<-list(diag.x=diag.x, diag.ind=ind.r) Using diag () Command to Construct Circulant Matrix. 2) If there is not already a current function how can my code be improved such that it is similar to the R diag where. A vector is a one-dimensional array and a matrix is a two-dimensional. You cannot use diag() to directly modify an existing array. MATLAB Arrays - All variables of all data types in MATLAB are multidimensional arrays. u2 + v2 ans 1 MATLAB uses double-precision oating point arithmetic. R<-t(as.matrix(seq((1+k),stp_pt_r,by=1))) When you use the two-argument form of diag(), the second argument needs to be the number of the diagonal. In addition, you can use MATLAB, in conjunction with the word processing and. I guess, I have a two leveled question referring to diag in R and matlab.ġ) I was wondering if there was a way already developed to access different diagonals of matrices in R similar to the way it is done in Matlab (see ).Ģ) If there is not already a current function how can my code be improved such that it is similar to the R diag where diag(x = 1, nrow, ncol) # returns the values of the diagonalĬ<-t(as.matrix(seq((1+k),stp_pt_c,by=1)))
