Hello
I was wondering if there is a way to get a scatter plot by just plugging in the matrix as opposed to
scatter(x,y,z) %Assuming the matrix has three columns
The columns of the matrix still represents the values for each axis, but I do not want to have to index like this: x=Matrix(:,1) y =Matrix(:,2) z=Matrix(:,3)
Is there a command like the following: somecommand(Matrix) and I get the same results?
Thank You

I am sorry I meant x=Matrix(:,1), etc

Not easily, but the disperse function from the user's group (see https://au.mathworks.com/matlabcentral/fileexchange/33866-disperse) helps in these situations.
[x,y,z] = disperse(Matrix);
scatter(x,y,z)

If you had a matrix with more than 3 columns, then what should be used for the X axis and what should be used for the Y axes and what should be used for the Z axes ? For example, if the matrix had 5 columns, then what would the equivalent scatter() commands be ?

I suppose one constraint is that the max number of columns the matrix can have is 3 columns in the order of x y z. And if thats the case I'd think that if statements could be used. But I still wonder if there is a more elegant way. Thank you
