You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: ica_fuse_interp.m
    path of file: ./repos/fit/FITv2.0e/ica_fuse/ica_fuse_utilities
    
    the code of the file until where you have to start completion: function [odata,b] = ica_fuse_interp(idata,r,l,cutoff)
%INTERP Resample data at a higher rate using lowpass interpolation.
%   Y = INTERP(X,R) resamples the sequence in vector X at R times
%   the original sample rate.  The resulting resampled vector Y is
%   R times longer, LENGTH(Y) = R*LENGTH(X).
%
%   A symmetric filter, B, allows the original data to pass through
%   unchanged and interpolates between so that the mean square error
%   between them and their ideal values is minimized.
%   Y = INTERP(X,R,L,CUTOFF) allows specification of arguments
%   L and CUTOFF which otherwise default to 4 and .5 respectively.
%   2*L is the number of original sample values used to perform the
%   interpolation.  Ideally L should be less than or equal to 10.
%   The length of B is 2*L*R+1. The signal is assumed to be band
%   limited with cutoff frequency 0 < CUTOFF <= 1.0. 
%   [Y,B] = INTERP(X,R,L,CUTOFF) returns the coefficients of the
%   interpolation filter B.
