How to create points set on 2D polyline

Dear All,

I would like to write a code which creates point feature or matrix on the line with specific sampling interval.

For example as seen below code I have 7 point coordinates (x,y),

Now the problem is I would like to increase these point set with giving sampling interval of point 0.1.

Then create new points set.

data= [0 0;
    1 1;
    2 2;
    3 2;
    4 1;
    5 1.25;
    6 3.25];
figure
plot(data(:,1),data(:,2),'r+');

Thanks in advance.

Mustafa

I have found the solution.

Linear interpolation is ok for this purpose.

data= [0 0;
    1 1;
    2 2;
    3 2;
    4 1;
    5 1.25;
    6 3.25];
figure
plot(data(:,1),data(:,2),'r+');
hold on
xq= min(data):0.1:max(data);
yq = interp1(data(:,1),data(:,2),xq);
plot(xq,yq,'k o');
