Print an array of coordinates with 2 Arrays of Varriables.

I have two Arrays of multiple numbers lets call it X and Y. I Need to make another array of numbers displayed as cordinates. So let's say that X[150 200 300 500] and Y[300 500 800 300] I need an array like [150,300 200,500 300,800 500,300]. the purpose is then to copy the data and paste to Autacad to make a polyline. Is there a simple way to do this ? I appriciate any kind of help.

Simple in Matlab

X = [150 200 300 500]';
Y = [300 500 800 300]';

coords = [X,Y]

coords =

   150   300
   200   500
   300   800
   500   300

Thanks alot but. the X and Y data for one variable needs to be printed in one column with the comma in between so the fyrst array should be printed as 150,300

You are looking for a string output, not numeric?

[Michael]

I am going to assume you are looking for a string output. Here is how I would do it.

X = [150 200 300 500]';
Y = [300 500 800 300]';

thematrix = [X,Y]';
asvector = thematrix(:);
stringvector = num2str(asvector);

comma_vector = repmat(', ',1,numel(X))';

blah = [stringvector,comma_vector]';

XY = ['[',blah(1:end-1),']']%end-1 is to get rid of last space

This would produce the output:

XY = '[150,300 200,500 300,800 500,300]'

Thanks alot ! Is there any way to print the resault in a new row ? just to make it more neat :D for example

XY =

150,300

200,500

300,800

500,300

[Michael]

Add a new line character and use the fprintf command:

X = [150 200 300 500]';
Y = [300 500 800 300]';
thematrix = [X,Y]';
asvector = thematrix(:);
stringvector = num2str(asvector);
comma_vector = repmat(',\',1,numel(X))';
return_vector = repmat(' n',1,numel(X))';
blah = [stringvector,comma_vector,return_vector]';
%XY = ['[',blah(1:end-1),']']
fprintf(blah(:)')

Produces this in the command window:

150, 300
200, 500
300, 800
500, 300

Please remember to accept this answer.
