picking numbers with specific difference in matlab

2 views (last 30 days)
I have a data set...like say CAD from 212 to 550 say with a differnce of 1 and have corresponing SA values to these CAD values
But I want to pick numbers at a specific distance and in a specific sequence ..like 212,212.3,212.7,213,213.3,213.7.....so that later on i can interpolate the SA values on these CAD values.
How can i do that!! if there was single difference between numbers that would be simple as i did here picking data with a differenc of 0.5:
CAD= data(:,1);
SA= data(:,2);
CADQ=CAD(1):0.5:CAD(end);
vq = interp1 (CAD, SA, CADQ);
here i was able to pick 212,212.5,213,213.5....and was able to interpolate SA on these CAD values.
now how can i do that..picking CAD data in the sequence 212,212.3,212.7,213,213.3,213.7,214,214.3.....

One way is to take advantage of implicit expansion.
x = 212:215;
y = [0; 0.3; 0.7];
z = reshape(x+y, 1, [])
z = 1×12
212.0000 212.3000 212.7000 213.0000 213.3000 213.7000 214.0000 214.3000 214.7000 215.0000 215.3000 215.7000

Yes it worked perfectly...so we can use this code to interpolate any repetitive values....Thanks
