D = diag(v) returns a square diagonal matrix with the elements of vector v on the main diagonal. example. D = diag(v,k) places the elements of vector v on the k th diagonal. k=0 represents the main diagonal, k>0 is above the main diagonal, and k<0 is below the main diagonal. example. x = diag(A) returns a column vector of the main diagonal ...writematrix(A) writes homogeneous array A to a comma delimited text file.The file name is the workspace variable name of the array, appended with the extension .txt.If writematrix cannot construct the file name from the array name, then it writes to the file matrix.txt.

No, not using writematrix () . The widths are controlled by metadata about the cells that writematrix () makes no attempt to control. In order to control the widths, you would need to be using MS Windows with Excel installed, and you would have to use activex to connect to excel and give it commands to control the cell formatting.Open in MATLAB Online. I have a 46 x 46 matrix and I want to export the data with headers. Currently I am using xlswrite but it doesn't seem very stable and the file takes a long time to open. Theme. Copy. RowNames = cellstr (headers); col_header= RowNames'; row_header= RowNames; xlswrite ('TtestResults.xls',results,'Sheet1','B2');I want to copy an Excel file to a different path through Matlab and then write in it also using Matlab. Somehow I get the error: Name cannot be the same as built-in name. As I want to write multiple times in the file, I don't want to solve this problem manuelly each time, I want the code to run through without me having to do something constantly.If you are using Matlab 2019, you could use the following recommended function to write a matrix to a set of files. Theme. Copy. writematrix (a,'a.csv'); writematrix (b,'a.csv','WriteMode','append'); But there is no option to add a separator line or headline in between. If you want to read the .csv file, use the following function.

One way to solve the equation is with x = inv(A)*b . A better way, from the standpoint of both execution time and numerical accuracy, is to use the matrix backslash operator x = A\b . This produces the solution using Gaussian elimination, without explicitly forming the inverse. See mldivide for further information.M= [h;num2cell (A)] hadiqa khan. Busra Unlu. Sign in to comment.
