Add Interpolated Vector to Matrix

Hi,

I'm trying to interpolate velocity values over a range of heights and times to then save it into a matrix. I'm having trouble getting the data to save/interpolate properly.

When I used Ninterp(:,t) = interp2(ADCP.t,ADCP.Depth,ADCP.N,time_in,Z); I was able to get it to work for t=1:1:100, however I need it to work for different time steps then just 1.

ADCP.N - North velocity values as a function of depth and time (82x1000)

ADCP.t - datenum time vector from the sensor

ADCP.Depth - depth of water column

time_in - an arbitrary time vector (may not be an integer) to interpolate through

Z - an arbitrary range of heights to interpolate through

Z = [150:-1:1];
Nq = zeros(length(ADCP.t));
for t=1:.25:100
    time_in = tStart+datenum([0,0,0,0,0,t]);
     Ninterp = interp2(ADCP.t,ADCP.Depth,ADCP.N,time_in,Z);
    Nq = Ninterp(t) 
end

Z = [150:-1:1];
Nq = zeros(length(ADCP.t));
t=1:0.25:100;

clear Ninterp
for i=length(t):-1:1
    
     time_in = tStart+datenum([0,0,0,0,0,t(i)]);
    
     Ninterp(:,i) = interp2(ADCP.t,ADCP.Depth,ADCP.N,time_in,Z);
   
end

Works perfect. Thank you!
