gpu arrayfun don't support linspace or NaN array

example code is:

gn   = rand(1000,"gpuArray")/100 + 0.995; 
offs = rand(1000,"gpuArray")/50  - 0.01;
meas = ones(1000)*3; % 1000-by-1000 matrix
corrected = arrayfun(@MC_OceanLidar_sub,meas,gn,offs);
results = gather(corrected);

function c = test(rawdata, gain, offset)
    layer=1:0.2:100;
    c = (rawdata .* gain) + offset + max(layer);
end

the error message is:

Function passed as first input argument contains unsupported or unknown function 'test'.

or

function c = test(rawdata, gain, offset)
    layer=NaN(10000,1,'single');
    c = (rawdata .* gain) + offset + max(layer);
end

the error message is :

Size inputs are not supported when using 'NaN'. Input to 'NaN' must be a valid class specification such as 'single' or 'double', or the

word 'like' followed by a prototype argument.

You cannot create an array inside a call to GPU arrayfun, only scalars.

Thanks, I got it!
