How to Get Vector of Integer

Hi,

I am new for matlab , can any one let me know how i can form vector of Integer with Comma .

Example :

   for int i =1:2

    matrix=[coordinate_x;ordinate_y;ordinate_z;ordinate_xx;ordinate_xy;ordinate_yy;ordinate_zx;ordinate_zy;];
  %1-by-8 matrix
  disp(matrix(:));

end

Result is of Matix is

            29
            45
           140
            45
            82
            12
            82
            80

            39
            65
            40
            75
            92
            02
            32
            80

Note 1 : I would like to form like matrix =[29,45,140,45,82,12,82,80] [39,65,40,75,92,02,32,80]

Commas add columns within the same row. Semicolons add another row:

matrix =[29,45,140,45,82,12,82,8; 39,65,40,75,92,02,32,80]

matrix will be a two row matrix. The second row starts after the semicolon.

Yes You are right ...when i add comma i have get result below like ?

if true
  % code
matrix
Columns 1 through 7

          28          40         158          40          79           1          79

Column 8

          68
  end

if true
  % code
matrix
Columns 1 through 7

           1          46         126          46          82           1          82

Column 8

          76
  end

Note:please let me know how i can form in array with comma each column? matrix =[28,40,158,40,79,1,79,68]

I thought I did. You're not giving exact syntax of either a statement of code, or how it spits things out to the command window so perhaps I guessed wrong at what you're looking to get. This is what I get:

>> matrix =[29,45,140,45,82,12,82,8; 39,65,40,75,92,02,32,80]
matrix =
    29    45   140    45    82    12    82     8
    39    65    40    75    92     2    32    80

The first is the line of code and because I didn't put a semicolon at the end of the line to suppress output, it sends the output to the command window and that is what shows up. Now, exactly what did you want, if it's not that?

"form in array with comma each column" does not make grammatical sense. Perhaps you can get a native English speaker to look it over. Maybe you want a string or character array - that's the only way you can have commas because a numerical matrix is just a collection of numbers:

outputString = sprintf('%d, ', matrix);

Thank's for reply me , now i have got each column with comma , now i want to add [] . example :

if true
  % code
outputString = sprintf('%d, ', matrix);
>> disp(outputString)
29, 45, 140, 45, 82, 12, 82, 8, %How to remove last column 8  comma ? also in between arrange [] array. 
end

[Image Analyst]

outputString1 = sprintf('%d, ', matrix(1,:));
outputString2 = sprintf('%d, ', matrix(2,:));
outputString = sprintf('[%s] [%s]', outputString1, outputString2);

Seems like a weird thing to want to do, but whatever...

[SAMEER ahamed]

Thank you so much reply to me ...Now I got below result like .

Example :

disp(outputString);
  outputString =[1, 2, 3, 4, 5, 6, 7, 8, ][1, 2, 3, 4, 5, 6, 7, 8, ];

*Note-1 : May i know how i can remove comma after 8 .

Note-2 : I would like to get like outputString =[1, 2, 3, 4, 5, 6, 7, 8][1, 2, 3, 4, 5, 6, 7, 8];*

I ran into the same problem. Here's a code snippet on how I solved it.

matrix =[29,45,140,45,82,12,82,8; 39,65,40,75,92,02,32,80]
[r,c] = size(matrix);
sprintf([ '[' [repmat('%d,', 1, c-1) repmat('%d', 1, 1)] ']'], matrix')

The output is

[29,45,140,45,82,12,82,8][39,65,40,75,92,2,32,80]

Note, there's no semicolon after the sprintf statement; this emits the output to the console. The first argument in the sprintf() is creating a format string to print the values of each row of the matrix. If c=2, then the format string '[%d, %d]' is created. If you need carriage returns in between each row, you can do the following.

sprintf([ '[' [repmat('%d,', 1, c-1) repmat('%d', 1, 1)] ']\n'], matrix')
