Dears,
It seems that elementary question but It tooks me a while to creat a new multi dimensional matrix in matlab script which is neatly spaced.Can anyone help me in fixing it?
MultD_matrix=[...
1 0 0 0 3 1 0 12.66 1.1 0.9
2 0 0.6 0 3 1 0 12.66 1.1 0.9
3 0 0 0 3 1 0 12.66 1.1 0.9
4 0 0.9 0 3 1 0 12.66 1.1 0.9
5 0 0 0 3 1 0 12.66 1.1 0.9
6 2.6 2.2 0 3 1 0 12.66 1.1 0.9
7 40.4 30 0 3 1 0 12.66 1.1 0.9
8 75 54 0 3 1 0 12.66 1.1 0.9
9 30 22 0 3 1 0 12.66 1.1 0.9
10 28 19 0 3 1 0 12.66 1.1 0.9
11 145 104 0 3 1 0 12.66 1.1 0.9
12 145 104 0 3 1 0 12.66 1.1 0.9
13 8 5.5 0 3 1 0 12.66 1.1 0.9
14 8 5.5 0 3 1 0 12.66 1.1 0.9
15 0 0 0 3 1 0 12.66 1.1 0.9];
FYI while I copy and paste my sscript code here,it automtacially creat neat spacing ,you can check the attched file

>> disp(num2str(MultD_matrix, '%g '))

15 0 0 0 3 1 0 12.66 1.1 0.9
And then copy and paste that into your code.
You can also use, for example,
disp(num2str(MultD_matrix, '%7g'))

No. You can copy the output of the num2str() with your mouse and paste it over your existing matrix.
Otherwise what you are asking me to do is write some code that will read in your .m file, find the matrix, reformat it, and write out the matrix again. That can be done, but I am not going to spend 20+ minutes writing it and testing it just to save you a few keystrokes. My code would have to worry about possibilities such as there appearing to be an assignment to the matrix but which was really commented out with % comments, or which was really commented out with %{ block comments, or which was part of a character vector, or about strange possibilities such as you having coded
MultD...
