linear and nearest neighbor interpolation

function output = calculateBlackLevel(blStruct, AG, ET)
blLut = zeros(length(blStruct), size(blStruct{1}.black_level,2));
etLut = zeros(length(blStruct), 1);

for k = 1 : length(blStruct)
bl = blStruct{k};

if length(bl.analog_gain) == 1
blLut(k, :) = bl.black_level;
elseif AG > max(bl.analog_gain) || AG < min(bl.analog_gain)
blLut(k, :) = interp1(bl.analog_gain, bl.black_level, AG, 'nearest', 'extrap');
else
blLut(k, :) = interp1(bl.analog_gain, bl.black_level, AG);
end

etLut(k) = bl.exposure_time;
end

if length(etLut) == 1
output = blLut;
elseif ET > max(etLut) || ET < min(etLut)
output = interp1(etLut, blLut, ET, 'nearest', 'extrap');
else
output = interp1(etLut, blLut, ET);
end
end

here is the matlab code i'm trying to convert, my question is. does ipp have any sort of interpolation functions?
