cut samples - interpolation
Aucune licence
A useful function for putting irregular spaced data on a regular spaced axis. Also works when the data locally has higher sampling resolution than the desired.
Example:
%create fake irregular spaced data
x=sort(rand(30,1));
y=sin(x*5)+randn(30,1)*.3;
%define the start and end intervals we want to have representative values of.
xsi=(-.2:.3:1.3)';
xei=xsi+.3;
%cut data into intervals ranging from xsi to xei:
yi=cutsamples(x,y,xei,xsi);
